Abstract
Provided is a laminate film having excellent bonding properties, resistance to water whitening, and chemical resistance, and containing a fluororesin layer comprising a fluororesin composition, and an acrylic resin layer comprising a resin composition that contains a reactive group-containing acrylic resin, acrylic rubber particles, and a thermoplastic resin.
Claims30
A laminate film comprising:
- a fluororesin layer (I) which is formed from a fluororesin composition (A);
- and
- an acrylic resin layer (II) which is formed from a resin composition (B) containing a reactive group-containing acrylic resin (B-1), wherein
- the resin composition (B) contains 10 to 100% by mass of (B-1), 0 to 90% by mass of acrylic rubber particles (B-2) other than (B-1), and 0 to 90% by mass of a thermoplastic resin (B-3) having a mass average molecular weight of less than 400,000 other than (B-1) and (B-2) with respect to the total 100% by mass of (B-1), (B-2), and (B-3), and further contains 0 to 50 parts by mass of an additive (C) other than (B-1), (B-2), and (B-3) with respect to the total 100 parts by mass of (B-1), (B-2), and (B-3),
- a gel fraction of the resin composition (B) is in the range of 10 to 80% by mass,
- the reactive group-containing acrylic resin (B-1) contains a monomer unit having a reactive substituent with respect to an amino group or methylol group, and
- a content of the monomer unit having the reactive substituent is 4% by mass or more with respect to 100% by mass of the resin composition (B).
