摘要： 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.

摘要： The object of the present invention is to provide a soldering-flux-oriented novel base resin that enhances the fluidity of a soldering flux and both the visco-stability and adhesion of a solder paste, while improving the color tone and anti-crack property of the flux residue. The present invention is directed to a base resin for a soldering flux, the base resin comprising a rosin (A) containing at least 15 wt % of a pimarane-type resin acid (a-1), at least 1 wt % of a labdane-type resin acid (a-2), and at least 50 wt % of an abietane-type resin acid that has no conjugated double bond (a-3).
