摘要:
The present invention discloses a water-dispersion type pressure-sensitive adhesive composition, a method for producing the same, and a pressure-sensitive adhesive product employng the same. With the present invention, the hydrophilic nature of dispersant (C) can be nullified by reacting a compound (B), containing a metal having a valence of at least two or having a specific functional group having reactivity, with the functional groups of dispersant (C), with the result that while being a water dispersion type pressure-sensitive adhesive composition, it displays excellent water resistance properties on a par with pressure-sensitive adhesives made from solvent type pressure-sensitive adhesive compositions.
摘要:
Disclosed herein are crosslinked spherical fine particles having good toughness, elastic properties, and chemical properties, and a process for producing the same, said fine particles being obtained by radical polymerization in the suspended state of a component [M] capable of radical polymerization containing a vinyl group-containing compound (V) capable of radical polymerization which is obtained by reaction of (a) a selected polyol, (b) an isocyanate group-containing compound, and (c) an active hydrogen-containing vinyl monomer capable of radical polymerization. Also disclosed herein are the secondary products of the crosslinked spherical fine particles, which include a coating composition and its derivatives (such as filmlike article, sheetlike article, adhesive filmlike article, and adhesive sheetlike article) and a peelable pressure-sensitive adhesive and peelable pressure-sensitive adhesive article.
