ADHESION IMPARTING AGENT, MEDICAL OR INDUSTRIAL ADHESION IMPARTING AGENT, MEDICAL OR INDUSTRIAL ADHESIVE.BONDING AGENT, MEDICAL OR INDUSTRIAL ADHESIVE.BONDING SHEET, AND MEDICAL OR INDUSTRIAL ADHESIVE TAPE
This invention provides a resin acid ester series adhesion imparting agent, having good compatibility with a synthetic rubber elastomer so that its melt viscosity is reduced, and is imparted with an excellent adhesive/bonding characteristic.The adhesion imparting agent uses an ester composition that contains a resin acid ester represented by the general formula (1) in the amount of 70 weight % or more, and has a 1H-NMR spectrum ratio (S’NMR / SNMR) of a proton integral value (S’NMR) in the region of 6 to 8 ppm to the total proton integral value (SNMR), of at least 6 %.本發明提供一種樹脂酸酯系之黏著賦予劑,其係可與合成橡膠彈性物良好地相溶,使其熔融黏度降低,而可賦予優異的黏/接著特性者。作為黏著賦予劑,係使用通式(1)所示之樹脂酸酯含量為70重量%以上,且1H-NMR光譜之全部質子積分值(SNMR)中之6至8ppm區域之質子積分值(S’NMR)的比率(S’NMR/SNMR)以百分率計為至少6%之酯組成物;
