Abstract
The present invention relates to a thermoplastic multilayer adhesive film including the following resin layer A and the following resin layer B, resin layer A is a layer containing a carboxylic acid-modified polyolefin and/or an ionomer, and resin layer B is a layer containing one or more selected from a carboxy-modified styrene-butadiene copolymer, a carboxy-modified acrylonitrile-styrene-butadiene copolymer, and a carboxy-modified methyl methacrylate-butadiene copolymer, and a crosslinking agent.
Claims8
A thermoplastic multilayer adhesive film comprising the following resin layer A and the following resin layer B:
- resin layer A:
- a layer containing a carboxylic acid-modified polyolefin and/or an ionomer, and
- resin layer B:
- a layer containing one or more selected from a carboxy-modified styrene-butadiene copolymer, a carboxy-modified acrylonitrile-styrene-butadiene copolymer, and a carboxy-modified methyl methacrylate-butadiene copolymer, and a crosslinking agent.
A method for producing a thermoplastic multilayer adhesive film, the method comprising:
- a step of applying an aqueous composition containing a crosslinking agent and one or more selected from a carboxy-modified styrene-butadiene copolymer latex, a carboxy-modified acrylonitrile-styrene-butadiene copolymer latex, and a carboxy-modified methyl methacrylate-butadiene copolymer latex onto a resin layer A that includes a layer containing a carboxylic acid-modified polyolefin and/or an ionomer;
- and
- a step of drying water at a temperature at which the resin layer A does not soften or melt, and forming a resin layer B.
