    摘要: This invention is directed to an improvement of the label convertibility of all temperature pressure sensitive adhesives based on acrylic emulsion. It maintains clarity in the final finished product after drying. It offers good broad and low temperature adhesion performance on wide range of substrates. The base polymer in the all temperature pressure sensitive adhesives is an acrylic emulsion polymer. The converting improvement resides in adding a vinyl acetate homopolymer and/or copolymers that will not increase the glass transition temperature of overall PSA that do not adversely impact to low temperature adhesion. The combination of unique features of this invention offers advantages for high-speed production in pressure sensitive label and tape industries.
