Abstract
A laminating film has at least a surface layer and an adhesive layer deposited on a substrate, wherein the surface layer is provided by applying a coating made by blending together at least two types of emulsions. Emulsion polymers included in the emulsions may have different glass transition temperatures. A laminating method using the laminating film includes the steps of press-bonding the laminating film to a printed matter at a temperature not less than the glass transition temperature of the emulsion polymer with the higher glass transition temperature, and separating the laminating film from the printed matter thereafter.
Claims13
A laminating method comprising the steps of:
- providing a laminating film having a surface layer and an adhesive layer disposed on the surface layer, with the layers being deposited on a substrate, and the surface layer being formed by applying at least two types of emulsions blended together to the substrate, wherein the surface layer can be separated from the substrate, the emulsions having emulsion polymers with different glass transition temperatures;
- press-bonding the laminating film to a printed matter at a temperature not less than the glass transition temperature of the emulsion polymer with a relatively high glass transition temperature, and
- separating the laminating film from the printed matter thereafter.
A laminating film, comprising:
- a surface layer;
- and
- an adhesive layer disposed on said surface layer, with said layers being deposited on a substrate, wherein
- said surface layer is formed by applying at least two types of emulsions blended together to the substrate, and wherein
- said surface layer can be separated from the substrate.
A laminating film, comprising:
- a surface layer;
- and
- an adhesive layer disposed on said surface layer, with said layers deposited on a substrate,
- wherein said surface layer is comprised of at least two types of resins and has an islands-in-sea structure in which a first resin forms islands in a sea of a second resin, and wherein
- said surface layer can be separated from the substrate.
A laminating film, comprising:
- a surface layer;
- and
- an adhesive layer on said surface layer, with said layers deposited on a substrate, wherein said surface layer is comprised of at least two types of resins lacking a homogenous structure, and wherein
- said surface layer can be separated from the substrate.
