A method includes a step of applying an aqueous 2-package type first colored paint to form an uncured first colored coating film; a step of applying an aqueous 1-package type second colored paint to form an uncured second colored coating film; a step of applying a solvent-based 2-package type clear paint to form an uncured clear coating film; and a step of heating the uncured first colored coating film, the uncured second colored coating film and the uncured clear coating film to 75 to 100° C. to simultaneously cure these films. The solvent-based 2-package type clear paint contains a hydroxyl group-containing acrylic resin and a polyisocyanate compound in a ratio of 1.5 to 2.0 equivalents of isocyanate groups in the polyisocyanate compound relative to 1 equivalent of hydroxyl groups in the hydroxyl group-containing acrylic resin.

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.

A transparent peelable polyester film is provided having a base layer (B) with first and second surfaces. A layer (C) is applied on the base layer (B). A heat-sealable layer (A), peelable to APET AND RPET, is applied on the opposing surface of the base layer (B). The heat-sealable and peelable outer layer (A) is formed from (a) from 85 to 99% by weight of polyester and (b) from 1 to 15% by weight of other substances. The polyester is formed from 25 to 95 mol % of units derived from at least one aromatic dicarboxylic acid and from 5 to 75 mol % of units derived from at least one aliphatic dicarboxylic acid, and the polyester includes at least 10 mol % of units derived from linear or branched diols having more than 2 and the layer (C) includes crosslinked acrylate and/or methacrylate-based copolymers.

Coated panel with at least a substrate (2) and a top layer applied thereto (3), wherein the above-mentioned top layer (3) comprises at least a decor layer (4) and a translucent or transparent wear layer (5), characterized in that the above-mentioned wear layer (5) comprises a thermally cured acrylate resin or a thermally cured unsaturated polyester resin. Preferably, wherein thermal curing partially or completely cures the resin. In particular, wherein the above-mentioned acrylate resin or unsaturated polyester resin is at least partially cured by means of a thermally initiated radical crosslinking reaction. The invention further relates to a method for the production of such coated panels (1), in particular floor panels.

A powder coated substrate system includes a base substrate with integrated structural support flanges having a powder coated front surface; a powder coating resin applied to the substrate to create a textured powder coated front surface, the textured surface having a roughness; the textured powder coated flanged substrate attached to a frame; the textured surface is suitable for receiving a writing device thereon.

A method of forming a multilayer coating film with excellent flip-flop properties and smoothness and allowing formation of a high-design multilayer coating film. In a method of forming a multilayer coating film comprising: a low-brightness intercoating film; a first base coating film; a second base coating film formed on an object to be coated; and a clear coating film formed on the second base coating film; the first base coating film is obtained by applying a first aqueous base coating material, the second base coating film is obtained by applying a second aqueous base coating material containing a brightness pigment, the clear coating film, with specific compositions and properties, is formed on a low-brightness intercoating film by a wet-on-wet method and the multilayer coating film is heat cured to form a cured multilayer coating film.

A free radical curable automotive body primer is provided that has a color change corresponding to the progress of the cure process until a dry to sand condition has been attained and an internal colored guide coat that does not change color given its exposure to ambient air and as a result, has a different color on the surface of the primer than when in bulk, allowing for the detection and removal of low spots or other imperfections from a vehicle body by additional sanding of the inventive primer to remove oxidized guide coat colorant surface regions. The cure color change is achieved through resort to at least one color changing dye that reacts with a free radical cure initiator during the vehicle body priming process and changes color to indicate when the primer composition has achieved a level of cure so as to be dry enough to sand.
