Solvent-free acrylic resin composition, solvent-free acrylic pressure-sensitive adhesive, adhesive sheet and solvent-free acrylic resin composition using the same

摘要

Acrylic resin (A) as a solvent-free acrylic resin composition that has little viscosity increase due to heating, has excellent thermal stability, and can be applied thickly when used as an adhesive, and can obtain adhesives excellent in step tracking, corrosion resistance, and moisture heat and haze resistance. In the solvent-free acrylic resin composition containing ), the acrylic resin (A) contains 5 to 60% by weight of the structural site derived from the hydroxyl group-containing monomer (a1), and the acid value in the resin composition is 0.001 to 0.3 mgKOH/g. Provided is a formulation acrylic resin composition.
