Non-whitening emulsion pressure sensitive adhesives
摘要:
Water resistant, low haze acrylic emulsion pressure sensitive adhesive compositions for use in decorative, light management or optical articles are disclosed. These emulsion pressure sensitive adhesives comprise (a) 50-90% by weight n-butyl acrylate, and (b) 10-50% by weight 2-hydroxy ethyl acrylate, or 2-hydroxy ethyl methacrylate, hydroxy propyl acrylate monomer, or mixtures thereof. These emulsion pressure sensitive adhesives can be used in wet lamination processes, and exhibit less than 2% increase in haze, less than 2% increase in opacity and greater than 95% transmittance after the wet lamination process.
