Abstract
Embodiments provide an anchor coat agent, including: (P) a polymer comprised of: (p1) a structural unit derived from a (meth)acrylate having one or more of one or more types of backbones selected from the group consisting of a benzotriazole backbone, a triazine backbone, and a benzophenone backbone per molecule in an amount of 1-50 mol %, (p2) a structural unit derived from an alkyl (meth)acrylate in an amount of 30-95 mol %, and (p3) a structural unit derived from a hydroxyl group-containing (meth)acrylate in an amount of 1-50 mol %, provided that the sum of structural units derived from all constituent monomers is 100 mol %.
Claims16
A hard coat laminated film, comprising:
- a hard coat;
- an anchor coat;
- and
- a resin film layer in order from a surface on a side upon which sunlight is incident in an actual state of use,
- wherein the hard coat is formed of a coating material containing a polymer (A) consisting of:
- (a1) a structural unit derived from a (meth)acrylate having one or more of one or more types of backbones selected from the group consisting of a benzotriazole backbone, a triazine backbone, and a benzophenone backbone per molecule,
- (a2) a structural unit derived from an alkyl (meth)acrylate,
- (a3) a structural unit derived from a compound containing one or more isocyanate groups per molecule, and
- (a4) a structural unit derived from a hydroxyl group containing (meth)acrylate,
- wherein (a1) the structural unit is present in an amount of 47 parts by mass to 59 parts by mass with the sum of the structural unit (a1), the structural unit (a2), and the structural unit (a3) adding to 100 parts by mass, and
- wherein (a1) the structural unit is present in an amount of 10 mol % to 60 mol % with the sum of the structural unit (a1), the structural unit (a2), and the structural unit (a3) adding to 100 mol %, and
- (B) a polyfunctional (meth)acrylate, the amount of the (B) polyfunctional (meth)acrylate being 20 parts by mass or more and 600 parts by mass or less based on 100 parts by mass of the amount of the polymer (A), and
- wherein
- the anchor coat is formed of an anchor coat agent, comprising:
- (P) a polymer comprised of:
- (p1) a structural unit derived from a (meth)acrylate having one or more of one or more types of backbones selected from the group consisting of a benzotriazole backbone, a triazine backbone, and a benzophenone backbone per molecule in an amount of 1-50 mol %;
- (p2) a structural unit derived from an alkyl (meth)acrylate in an amount of 30-95 mol %;
- and
- (p3) a structural unit derived from a hydroxyl group-containing (meth)acrylate in an amount of 1-50 mol %, provided that the sum of structural units derived from all constituent monomers is 100 mol %.
