Title:
RADIATION-CURABLE HOT PRESSURE-SENSITIVE ADHESIVE AND ADHESIVE TAPE MADE THEREFROM
Document Type and Number:
Japanese Patent JP3281026
Kind Code:
B2
Abstract:

PURPOSE: To obtain the title adhesive for solvent-free application, excellent in adhesive power and holding power, and an adhesive tape made therefrom.
CONSTITUTION: A radiation-curable hot pressure-sensitive adhesive which contains 100 pts.wt. acrylic polymer containing at least 50wt.% acrylic monomer units represented by the general formula CH2=C(R1)COOR2 (wherein R1 is H or methyl; and R2 is 2-14C alkyl), 50-150 pts.wt. hot-melt resin having a melting point of 70-200°C, and 1-30 pts.wt. polyfunctional monomer having at least two radiation-reactive unsaturated bonds in the molecule; and an adhesive tape which has a layer of the adhesive on a support. Resticking of the tape and the correction in the sticking position can be made easily because of weak adhesive power at room temperature before heat treatment, and a strong adhesive power can be revealed by heat treatment at relatively low temperature, i.e., at about 100°C or lower, for a short time.
