<P>PROBLEM TO BE SOLVED: To obtain a self-adhesive suppressing generation of pulse peel when peeling a self-adhesive tape. <P>SOLUTION: An aqueous self-adhesive composition is used. The composition is obtained by polymerizing a component (B) in an aqueous dispersion containing a urethane prepolymer (A) obtained by reacting a chain aliphatic polyvalent isocyanate compound with a diol component, and a polymerizable monomer (B). The component (A) contains 0.5-50 wt.% of a specific silicon-based compound chain based on the total component (A), and the component (B) is a polymerizable monomer whose homopolymer has a glass transition temperature of -80 to 10°C. <P>COPYRIGHT: (C)2011,JPO&INPIT |
