The present invention relates to an infrared ray-transmitting photosensitive resin composition comprising a colorant, an alkali-soluble resin, a photopolymerizable compound, a photopolymerization initiator, and a solvent, wherein the infrared ray-transmitting photosensitive resin composition comprises at least one of a porphyrin compound and a chromatic colorant of a specific color. The infrared ray-transmitting photosensitive resin composition, according to the present invention, exhibits a high transmittance in the infrared region and a low transmittance in the visible light region, even in a thin film, and has excellent patterning properties. La présente invention concerne une composition de résine photosensible transmettant les rayons infrarouges comprenant un colorant, une résine soluble dans les alcalis, un composé photopolymérisable, un initiateur de photopolymérisation et un solvant, la composition de résine photosensible transmettant les rayons infrarouges comprenant un composé de porphyrine et/ou un colorant chromatique d'une couleur spécifique. La composition de résine photosensible transmettant les rayons infrarouges, selon la présente invention, présente une transmittance élevée dans la région infrarouge et une faible transmittance dans la région de lumière visible, même dans un film mince, et présente d'excellentes propriétés de formation de motifs. 본 발명은 착색제, 알칼리 가용성 수지, 광중합성 화합물, 광중합 개시제 및 용제를 포함하는 적외선 투과 감광성 수지 조성물로서, 포피린 화합물과, 특정 색상의 유채색 착색제 중 하나 이상을 포함하는 적외선 투과 감광성 수지 조성물을 제공한다. 본 발명에 따른 적외선 투과 감광성 수지 조성물은 박막에서도 가시광선 영역에서 낮은 투과율을 가지면서 적외선 영역에서는 높은 투과율을 나타내고, 패턴 특성도 뛰어나다.
