This invention provides a readily adhesive polyester film that has fewer flaws and in which no appearance defects occur due to tight winding during the storage of rolled products, and a method for efficiently producing the readily adhesive polyester film. More specifically, this invention provides a readily adhesive polyester film comprising a polyester film as a base film and a readily adhesive layer on at least one side of the base film, wherein the base film contains particles with an average particle diameter of 0.1-2 μm or more in an amount of 1 mass % or less based on the mass of the base film, and the readily adhesive layer is a cured product of a composition comprising a copolymerized polyester resin (A), a blocked isocyanate group-containing urethane resin (B), and a silicone surfactant (C). This invention also provides a method for producing a readily adhesive polyester film.

This adhesively-laminated core manufacturing method is a method for manufacturing an adhesively-laminated core by punching a plurality of steel sheet parts while a strip-shaped steel sheet is fed and laminating the steel sheet parts via an adhesive, and includes a step of forming a curing acceleration portion by applying and drying a curing accelerator on one or both surfaces of the strip-shaped steel sheet before a pressing oil is applied, and a step of applying the pressing oil to a surface of the curing acceleration portion.

Provided is a PET bottle preform in which delamination is suppressed and a method for the production of the preform. An anchor layer containing a polyester-based urethane resin is formed on an outer surface of the preform.

A process for manufacture of a profiled non-stick pan with a concave-convex pattern, which includes the following steps: preparing a flat blank for forming a pan body; screen printing a layer of ink with a predetermined pattern on a surface of the blank for a pan body, then drying and curing the ink; etching, by an etching process, the surface of the blank, on areas of the surface not covered by the ink, then cleaning and drying the blank, and retaining the ink; spraying non-stick pan coating on the blank, then baking the blank at high temperature, to enable the ink to automatically peel off at high temperature; pressing and stretching the blank to form a profiled pan body, then deburring and polishing on an edge of the pan body.

Disclosed is a non-stick coating for an article, particularly for a baking pan or other household and utility item, comprises at least a base layer (G) burnt onto a surface (O) of the article and a covering layer (D) burnt above the base layer. The base layer and the covering layer each have a dry film thickness of 1 to 25 μm, wherein the base layer contains 10 to 100 wt.-%, related to the weight of the burnt base layer, of a thermoplastic resin having a temperature resistance exceeding 200° C., and wherein the covering layer contains a thermoplastic resin having a temperature resistance exceeding 200° C. and optionally a silicone resin. Both the base layer and also the covering layer are free of perfluorinated and polyfluorinated alkyl compounds. Due to the fact that the covering layer comprises a content of thermoplastic resin of at least 30 wt.-%, related to the weight of the burnt covering layer, and of at least 2.5 wt.-%, related to the weight of the burnt covering layer, of a silicone oil, novel fluorine-free non-stick coatings with good substrate adhesion and very good deep-drawing properties are obtained. In a process for applying the non-stick coating, the base layer to be formed is applied as a liquid varnish onto the surface of the article and subsequently dried at 250 to 440° C., subsequently the covering layer is applied as liquid varnish onto the predried base layer, and finally the layers are bonded to each other and to the surface of the article by means of heat treatment at 250 to 440° C.

Provided is a PET bottle preform in which delamination is suppressed and a method for the production of the preform. An anchor layer containing a polyester-based urethane resin is formed on an outer surface of the preform.

This method of manufacturing an outer case for a hot water unit involves a pressing step for subjecting a flat metal plate (30a) to press processing to form a component part (3) of the outer case (C), and a painting step for painting text, symbols, figures or patterns on the component part (3), wherein the painting step involves an inkjet printing step for forming an inkjet printing layer (4) by performing inkjet printing on the flat metal plate (30a). The pressing step is performed after the inkjet printing step, and after the pressing step, there is further a clear coating step for forming a clear layer (5) on the inkjet printing layer (4).

The present invention discloses a super-flexible high electrical and thermal conductivity flexible base material and a preparation method thereof, wherein the method comprises the steps of: S1. carbonizing and blackleading a polyimide thin film, doping nano-metal to the polyimide thin film, and performing ion implantation and ion exchange; S2. performing plasma irradiation modification treatment on a surface of the material obtained after the step S1 to form a heterogeneous surface layer; and S3. forming a metal conductor layer on the heterogeneous surface layer by physical vapor deposition (PVD) or chemical vapor deposition (CVD), so as to obtain the super-flexible high-ductility high electrical and thermal conductivity flexible base material. The method can obtain the C-C-FPC, C-C-COF or C-C-FCCL flexible circuit base material with super flexibility, high ductility, high electrical conductivity, high thermal conductivity and high frequency performance.

A resin-coated steel can and method for producing the same. The resin-coated steel can is produced by drawing or draw-redrawing a resin-coated steel sheet at least having a surface serving as a can inner surface coated with a biaxially-stretched polyester film and a surface serving as a can outer surface that is coated and/or printed. The biaxially-stretched polyester film on the can inner surface side wall has a crystallinity in a range of 42 to 52%, and a shrinkage (shrinkage in the can height direction upon raising the temperature from 23 C. to 130 C. at a rate of 5 C./min.) of the biaxially-stretched polyester film on the can inner surface side wall is less than 10% of the can height.
