摘要

into the pale, no odor, and excellent stability, compatibility with various base polymers used in adhesives It has excellent tackifier, in particular providing a tackifier for the pressure-sensitive adhesive medical patch jeyong. In addition, for those that are likely to be sensitive to chemical reaction, more tackifier was conventionally used to provide a tackifier having a high stability. Furthermore, an excellent adhesive or glue adhesive properties, etc., in particular to provide a pressure-sensitive adhesive or adhesive formulations suitable for medical concubine. ; tablets obtained by the reaction of rosin acids and alcohols, the absorbance at 276nm of UV spectrophotometry A ( 1% 1cm) and has less than 4.5 19.5, ¹ 5.4 at H-NMR to give a pressure-sensitive adhesive which is characterized by containing the reaction product do not have a peak to 6.6ppm. ; tackifier, a purified rosin acids, alcohols, concubines Posay, dehydro abietic acid, the adhesive composition
