Title:
ACRYLIC EMULSION ADHESIVE COMPOSITION COMPRISING NANO SIZED LATEX PARTICLES HAVING A MONO-MODAL PARTICLE SIZE DISTRIBUTION, AND PRODUCTION METHOD FOR SAME
Document Type and Number:
WIPO Patent Application WO/2014/058199
Kind Code:
A1
Abstract:
The present invention relates to an acrylic emulsion adhesive composition which comprises latex particles wherein 3 or more different types of anionic emulsifiers cover polymer fine particles comprising (A) a main momoner consisting of a (meth)acrylic acid ester monomer having a C1-C14 alkyl group, (B) an auxiliary monomer consisting of one or more monomer selected from the group consisting of monomers comprising an alkyl ester, a vinyl ester, an unsaturated ester group or a mixture thereof and a cyano group, monomers comprising an amine group, and styrene-based monomers having a vinyl group,(C) a functional monomer consisting of a monomer having a carboxyl group and/or hydroxyl group, and (D) a crosslinking agent; and the composition has an outstandingly stable high-solids fraction in which the latex particles have a nano-sized mean particle size and monomodal form of particle size distribution. The present invention also relates to a production method for the acrylic emulsion adhesive composition.
