Title:
WATER-SOLUBLE PRESSURE-SENSITIVE ADHESIVE RESIN
Document Type and Number:
Japanese Patent JP3475452
Kind Code:
B2
Abstract:
PURPOSE: To obtain a water-soluble pressure-sensitive adhesive resin excellent in adhesion, and dissociative properties and releasability in the presence of water by using as the main component a copolymer prepd. from a plurality of specific compds. as the indispensable monomers and setting the glass transition temperature thereof at a predetermined value.
CONSTITUTION: A water-soluble pressure-sensitive adhesive resin has a glass transition temperature of -50 to 20°C and comprises as the main component a copolymer prepd. from an amino group-contg. (meth)acrylate, (meth)acrylamide or vinyl ether of the formula (wherein R1 is H or CH3; R2 and R3 are each H or 1-5C alkyl; n is 1 to 5; and X is an ester, amide or ether bond), and/or a quaternary salt thereof (e.g. N,N-dimethylaminoethyl acrylate), and a vinyl amide compd. of the formula: CH2=CHNHCOR4 (wherein R4 is R1) as the indispensable monomers, the total amt. of which is 50 to 100wt.% based on all monomers.
