Abstract
Abstract A structure for a synthetic resin-made molding for a bodies, bumpers, etc. of automobiles is adhered via a double-coated adhesive tape. Adhesives comprising chloroprene rubbers, isobutylene-isoprene rubbers and phenolic resins and primers comprising a mixture of at least one polymer selected from polyacrylic acid derivatives and polymethacrylic acid derivatives and chloroprene rubbers are coated and formed between the molding and the tape.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
237 words
A molding-bearing substrate, comprising: (a) a substrate having a surface adapted to have a molding adhered thereto; (b) a molding adapted to be adhered to said surface of said substrate; (c) a strip of tape having a first face and, opposed to said first face, a second face; (d) a first adhesive means interposed between said first face of said strip of tape and said surface of said substrate and adhering said strip of tape to said surface of said substrate; and (e) a second adhesive means interposed between said second face of said strip of tape and said molding and adhering said molding to said strip of tape, said second adhesive means comprising: (i) a layer of primer coated on said molding, and (ii) a layer of adhesive coated on said layer of primer, so that said layer of adhesive adheres to said second face of said tape, and said layer of primer adheres both to said layer of adhesive and to said molding; said layer of primer comprising a mixture of 10-500 parts by weight of at least one polymer selected from the group consisting of a polyacrylic acid derivative and a polymethacrylic acid derivative, and 100 parts by weight of chloroprene rubber, and said layer of adhesive comprising a mixture of 5-100 parts by weight of isobutylene-isoprene rubber, 1-50 parts by weight of a phenolic resin, and 100 parts by weight of chloroprene rubber.
Claim 2
Dependent Claim
237 words
A molding-bearing substrate, comprising: (a) a substrate having a surface adapted to have a molding adhered thereto; (b) a molding adapted to be adhered to said surface of said substrate; (c) a strip of tape having a first face and, opposed to said first face, a second face; (d) a first adhesive means interposed between said first face of said strip of tape and said surface of said substrate and adhering said strip of tape to said surface of said substrate; and (e) a second adhesive means interposed between said second face of said strip of tape and said molding and adhering said molding to said strip of tape, said second adhesive means comprising: (i) a layer of primer coated on said molding, and (ii) a layer of adhesive coated on said layer of primer, so that said layer of adhesive adheres to said second face of said tape, and said layer of primer adheres both to said layer of adhesive and to said molding; said layer of primer comprising a mixture of 10-500 parts by weight of at least one polymer selected from the group consisting of a polyacrylic acid derivative and a polymethacrylic acid derivative, and 100 parts by weight of chloroprene rubber, and said layer of adhesive comprising a mixture of 5-100 parts by weight of isobutylene-isoprene rubber, 1-50 parts by weight of a phenolic resin, and 100 parts by weight of chloroprene rubber.
Claim 3
Dependent Claim
95 words
The molding-bearing substrate of claim 1, wherein: said substrate is steel plate having an acrylic baking finish providing said surface thereof; said molding is made of a synthetic resin selected from the group consisting of polyvinylchloride, polyurethane, ethylene-vinyl acetate copolymer and vulcanized polyolefin rubber; said strip of tape is made of a material selected from the group consisting of foamed acrylic rubber, foamed polyethylene, non-woven cloth, kraft paper and synthetic resin film; said first adhesive means is made of acrylic adhesive; and said phenolic resin of said layer of adhesive is a novolak-type phenolic resin.
