Abstract

PROBLEM TO BE SOLVED: To obtain a heat-sensitive delayed-tack self-adhesive excellent in self-adhesive power, blocking resistance, etc., by compounding a thermoplastic acryl/butadiene copolymer with a tackifier and a solid plasticizer. SOLUTION: This adhesive is prepd. by compounding a thermoplastic acryl/ butadiene copolymer with a tackifier (e.g. a hydrogenated rosin) and a solid plasticizer (e.g. biphenyl phthalate). As the copolymer is used one made from butadiene and an acrylic monomer such as methyl methacrylate, methacrylic acid, acrylic acid, acrylonitrile, or acrylamide, an esp. pref. example being a methyl methacrylate/butadiene copolymer. A combination of a methyl methacrylate/butadiene copolymer with a styrene/acrylic copolymer can greatly improve the adhesive power, blocking resistance, etc.

2. Description of the Related Art Thermosensitive delayed tack adhesives are
Basically, thermoplastic resins and solid plastics are used, as described in "Practice Manual", 12th Edition, pages (131-135), Showa 55, published by Kobunshi Kogyokai. Agent and tackifier. Thermoplastic resins are the source of adhesive strength and adhesive strength, and solid plasticizers are
Since it is a solid at room temperature, it does not impart plasticity to the resin, but when added, it melts and swells or softens the resin to develop tackiness. Furthermore, the tackifier functions to improve the adhesive property. Since the solid plasticizer in the heat-sensitive delayed tack adhesive is crystallized slowly after being melted by heating, the adhesiveness is maintained for a long time even after removing the heat source.
However, the conventional heat-sensitive delayed tack adhesives do not have sufficient adhesive strength after the appearance of tackiness.
