In one embodiment, the process comprises providing a foil on a solid carrier in a foil provision stage, providing electronic wiring and an electronic component to the foil in an electronics provision stage, to provide said electronics, removing the solid carrier and arranging the foil on or in a liquid in a liquid application stage, and transferring the electronics to the 3D object in a transfer stage, as well as a 3D object obtainable by such process.

Provided are a single-layered hydraulic transfer printing base film, including 1.5 to 15 parts by mass of a plate or needle filler with an average particle diameter of from 2 to 14 m and an aspect ratio of from 4 to 60 based on 100 parts by mass of polyvinyl alcohol and a method of producing a hydraulic transfer printing base film, including forming a film using a liquid containing 1.5 to 15 parts by mass of a plate or needle filler with an average particle diameter of from 2 to 14 m and an aspect ratio of from 4 to 60 based on 100 parts by mass of polyvinyl alcohol. A hydraulic transfer printing base film that is not easily broken when fed from a roll and a method of producing the base film are thus provided.

A method for manufacturing a transfer sheet capable of forming a coat layer for protecting an image with high positional accuracy is provided. The method includes a step of printing an ink for forming an image on a water-soluble layer by an inkjet method to form an image layer, and a step of printing an ink containing a photocurable compound on the image layer by the inkjet method to form a coat layer, and the water-soluble layer, the image layer, or the coat layer contains a hot-melt inorganic substance.

A calculable 3D color printing method is used for generating, on a 3D object surface, a user-specified color texture pattern, including: performing modeling and simulated calculation with respect to a motion and a deformation of a PVA film in a traditional water transfer printing process to obtain a mapping function between each of pixels on the PVA film and points on an object surface; and calculating, by using the mapping function, a texture pattern to print on the PVA film. This disclosure further includes a set of mechanical devices and a 3D vision system for realizing precise and controllable water transfer printing which precisely prints a user-specified texture pattern onto an object surface. This disclosure further includes a multiple water transfer printing method, including: partitioning a complex object surface into a plurality of regions, and separately coloring each region, until eventually completing coloring of the entire object surface.

The present invention relates to articles such as plastic closures molded from polymeric materials the like having a hydro-graphic film applied thereto for enhancing aesthetic appeal. The present invention further relates to techniques for applying a coating to articles, such as plastic closures, with a hydro-graphic film ink, which method contemplates application of the ink to the articles in a water bath without first drying the ink, thereby maintaining the ink in fluid state, desirably avoiding the time-consuming and sometimes problematic steps of drying and reactivating the hydro-graphic film ink.

A coating machine has a receiving box, a releasing device, a length measuring device, a driving roller device and a coating device. The releasing device, the length measuring device, the driving roller device, and the coating device are assembled inside the receiving box. The coating device has a coating pole and a releasing set. The coating pole is arranged below the releasing set. The releasing set has a receptacle to contain an activator. The receptacle has at least one releasing hole to release the activator. The coating machine adopts the coating device with a simplified structure and has a merit of coating the activator evenly.

Methods for application of designs to devices such as headphones, earmuffs, and/or earplugs. At least one exterior surface of the device is painted, and a printed film is placed in a water tank at the water surface for separating the image from the film, such that the image is transferred to the exterior surface of the device. The device is rinsed and dried, and top coat applied. Alternatively, earplugs may have designs applied thereto utilizing a custom fixture configured to hold one or a plurality of devices concurrently with the exterior surface for decoration facing outwardly or upwardly and then transferring an image to the exterior surface using an indirect offset decorating process.

A method of water transfer printing is provided. The method including the following operations. A water transfer printing film is received. An information body is transferred to a printing substrate without use of an organic solvent-containing activator prior to transferring the information body. The water transfer printing film includes a superabsorbent film, a water-based resin layer on the superabsorbent film, the water-based resin layer, and the information body on the water-based resin layer. The information body includes a water-based colorant and a water-based resin.

A method enables a user to apply their own artistic input to a temporary tattoo design (TTD). The TTD is pre-printed on a substrate sheet which includes a synthetic oil which allows for: ease of coloring as the gel pen inks glide easily across the paper; transfer onto the skin with high-quality and vivid color results; and increased longevity of the temporary tattoo. The user first colors in the TTD with gel pens specifically designed and tested for transference onto the skin. Second, an adhesive coating is applied to the colored TTD. The colored TTD is transferred to the skin by placing the colored TTD with adhesive face-down on skin, slightly moistening the substrate with water and then removing the backing sheet. The synthetic oil added to the tattoo transfer sheet enables the colored temporary tattoo to remain on the skin for five to ten days.

[Problem] To provide a film that has excellent water solubility which changes little over time even when the film touches a chemical, a package and a liquid transfer printing film each using the film and a liquid transfer printing method using the liquid transfer printing film. [Means for Resolution] A film containing a hydroxymethyl group-containing vinyl alcohol-based polymer containing a vinyl alcohol unit and a unit structure represented by the following formula (1), a package and a liquid transfer printing film each using the film and a liquid transfer printing method using the liquid transfer printing film. ##STR00001##
