ADHESIVE COMPOSITION

摘要

An adhesive composition which contains an elastomer having a solubility parameter of 18.5MPa1/2 or below, a tackifier having a hydroxyl value of 20mgKOH/g or above, and a near infrared absorbing coloring matter. The tackifier content is adjusted to 100 to 250 parts by weight per 100 parts by weight of the elastomer. The adhesive composition exhibits pressure -sensitive adhesiveness and is excellent in the color fastness of the near infrared absorbing coloring matter.
