NEAR-INFRARED ABSORBING SYNTHETIC RESIN COMPOSITION

摘要

Provided is a near-infrared absorbing synthetic resin composition comprising a bipyrrolo isoquinoline compound represented by general formula (1) and a synthetic resin. In the formula, R1 and R2 are identical or different to each other, and represent a hydrogen atom, a halogen atom, or an optionally substituted C1-20 alkyl group, C1-20 alkoxy group, C6-20 aryl group, C7-20 arylalkyl group or C5-12 cycloalkyl group. The content of the bipyrrolo isoquinoline compound with respect to 100 parts by mass of the synthetic resin is preferably 0.001-20 parts by mass.
