The pre-treatment fixing further includes a co-solvent, a surfactant, and a balance of water. The surfactant is selected from the group consisting of a first surfactant having a first hydrophilic lipophilic balance (HLB) value within a hydrophobic range and a combination of the first surfactant and a second surfactant having a second HLB value within a water dispersible range.
WATER-DISPERSIBLE SHEET
The present invention provides a water-dispersible sheet with a suppressed time degradation of the tacky adhesiveness of the tacky adhesive layer, while maintaining the water dispersibility.
The time degradation of the tacky adhesiveness of the tacky adhesive layer of a water-dispersible sheet can be suppressed, while maintaining the water dispersibility of the water-dispersible sheet, by using a paper substrate of the water-dispersible sheet with a multilayer structure, wherein one of the multilayer (inner layer) which is not in contact with a tacky adhesive layer and the other layer (surface layer) which is in contact with the tacky adhesive layer comprise independently a mixed pulp of a wood pulp and a refined pulp with -cellulose content of 88% by weight or more, wherein the weight ratio of these layers and the beating degree of the mixed pulps are set in the specific ranges. Provided is a water-dispersible sheet comprising a paper substrate comprising an inner layer and at least one surface layer, wherein a tacky adhesive layer is installed on one of the surface layer (hereinafter referred to as first surface layer), wherein the first surface layer comprises a mixed pulp 1, which comprises a wood pulp and a refined pulp with -cellulose content of 88% by weight or more, wherein the Canadian standard freeness of the mixed pulp 1 is from 450 to 600 ml CSF, the content of the wood pulp in the mixed pulp 1 is from 50 to 95% by weight, the inner layer comprises a mixed pulp 3, which comprises a wood pulp and a refined pulp with -cellulose content of 88% by weight or more, wherein the Canadian standard freeness of the mixed pulp 3 is from 600 to 750 ml CSF, and the content of the wood pulp in the mixed pulp 3 is from 50 to 95% by weight.
SYNTHETIC RUBBER TILE WITH THERMAL RESISTANCE MODULATION
A prefabricated tile-type coating, whose manufacture is based on the development of a polymeric composite including mainly recycled synthetic rubber obtained from the grinding of scrap automotive waste tires, virgin rubber, or a combination of both, using as a binder a novel cross-linkable acrylic resin with the ability to be processed by pultrusion. The upper layer of the tile is made of a resin with thermochromic effect that integrates an encapsulated pigment of thermochromic material with a transition temperature in the range of 20-35 C. which changes color from white under high-temperature conditions, i.e. C. or greater than dark in conditions of low temperature, that is, 20 C. or less. The tile of elastomeric character obtained has notable competitive advantages compared to other technologies in terms of thermal resistance, solar reflectance, and resistance to the impact caused by hail or other meteorological phenomena.
DEGRADABLE CONTAINMENT FEATURES
A degradable containment includes an outer structural layer constructed of a pulp material, a central carrier layer constructed of a biopolymer, and an interior nanomaterial layer constructed of a nanomaterial.
AQUEOUS ETHYL CELLULOSE DISPERSION
There is provided an aqueous dispersion comprising 40-90 wt-% ethyl cellulose and 10-50 wt-% at least one plasticizer, and to a film having water barrier property produced from the dispersion. Additionally, there is provided a fiber based substrate comprising at least one film layer produced from the aqueous dispersion.

INKJET INK AND INKJET RECORDING METHOD
An inkjet ink contains a pigment, a water-soluble organic solvent, water, and a surfactant. The water-soluble organic solvent includes a glycol ether compound. A difference between a dynamic surface tension ?.sub.10 of the inkjet ink at a surface age of 10 milliseconds and a dynamic surface tension ?.sub.10000 of the inkjet ink at a surface age of 10000 milliseconds is no greater than 3.4 mN/m. An inkjet recording method is an inkjet recording method for forming an image on a recording medium with the above-mentioned inkjet ink and includes forming the image by ejecting the inkjet ink toward the recording medium. The recording medium is a poorly absorbent recording medium.
STAMPING PRINTING PROCESS BY IMAGE TRANSFER WITH SPECIALLY COATED PAPER AND SUBLIMATION INK
The present invention is a press-printing method for image transfer with a specially coated paper and sublimation ink, in which a pattern or image is printed on a paper coated with the special coating for subsequent transfer to the object to be printed. When used in an ink jet printing, screen printing, gravure printing or flexographic printing process, the coating prevents the printed ink from permeating the paper due to paper porosity. The image transfer from the coated paper to the object to be printed is performed by pressure and heat at a temperature between 200 C. and 230 C., wherein the coating is activated by the heat, so that the coating becomes soft and adjusts to the printing surface and is easily adhered to it. This allows a direct transfer of the sublimation ink to the contact area of the surface to be printed, which makes the coating superior to other coatings on the market.
