摘要

An acrylic pressure sensitive adhesive or pressure sensitive adhesive tape that is preferably employed in the bonding and fixing of members utilized in a closed space of vehicles, houses, etc. wherein odor is a problem or in an internal part of electronic equipment wherein volatile gas is a problem; and an air conditioner unit for vehicles comprising the same. The acrylic pressure sensitive adhesive is one exhibiting a volatile component concentration (A) of 500 ppm or less when heated at 90ºC for 30 min, the volatile component concentration (A) calculated by the formula: Volatile component concentration A (ppm) = [Amount of volatile component X (mug)] / [Weight of pressure sensitive adhesive before heating Z (g)] (1) wherein the amount of volatile component X is the amount in terms of toluene.
