  • Pressure-sensitive adhesive composition and acrylic pressure-sensitive adhesive composition
    Patent number: 10253215
    Abstract: An object of the present invention is to provide an adhesive composition that is substantially odorless and has an extremely good color and excellent adhesive properties or tack at low temperatures of about 5° C. and in which deterioration over time caused by heat or light is suppressed. The present invention relates to an adhesive composition comprising a liquid rosin ester compound, the liquid rosin ester compound being obtained by reacting a rosin compound with a C1-10 monohydric alcohol compound and having a Gardner color of 1 or less, a glass transition temperature of ?20° C. or less, a degree of esterification of 93 wt % or more, and a ratio (Y?/Y) of the total area of peaks in 16- to 22-min retention time region (Y?) to the total area of all the peaks (Y) measured by gas chromatography under the following conditions of 200 ppm or less.
    Type: Grant
