Adhesive constituent
Document Type and Number:
Japanese Patent JP6270551
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an acrylic aqueous emulsion type adhesive having the same level of autohesion and low tackiness as a natural rubber based adhesive.SOLUTION: An aqueous emulsion type adhesive containing the following (A) and (B) constituents with a weight ratio (A)/(B) within the range of 5/95 to 50/50 is used. (A) is a (meth)acrylic polymer having 90 wt.% or more of a tetrahydrofuran insoluble mater, and a glass transition point of -50°C to -20°C. (B) is an ethylene- vinyl acetate- vinyl neodecanoate terpolymer having a content weight ratio (B1/B2/B3) of ethylene (B1)/vinyl acetate (B2)/vinyl neodecanoate (B3) of within the range of 2-25/10-70/10-88, where the total amount of the three constituents is 100.
