JP2739152B

PURPOSE:To obtain a reactive tacky agent composition, consisting of a saturated polyester resin which is a solid at ordinary temperature, etc., (meth)acrylic urethane monomer having a specific viscosity at ordinary temperature, etc., having moderate tackiness at ordinary temperature and curable with light, etc., to provide strong adhesive force. CONSTITUTION:A reactive tacky agent composition, obtained by dissolving (A) one or more of a saturated polyester resin, acrylic rubber, acrylic elastomer, polybutadiene and acrylic tacky agent and (B) one or more of an acrylic or methacrylic urethane monomer, oligomer and other (meth)acrylic monomers and oligomers which are a solid at ordinary temperature having >=10 cP viscosity at ordinary temperature in a solvent and drying the solvent and suitable as sealing media. Furthermore, one or more of photo- or thermosetting catalyst or further magnetic substance, electric conductor, fluorescent substance, etc., are preferably contained in the above-mentioned components.
