摘要： The present invention provides a photosensitive composition comprising an infrared absorbing agent represented by the following formula (I) and a polymer compound which is insoluble in water and soluble in an aqueous alkali solution and becoming soluble in an aqueous alkali solution by radiation of an infrared laser. In the formula described below, R1 and R2 independently represent an alkyl group having 1 to 18 carbon atoms or an alkyl group having 9 to 30 carbon atoms and Z represents a heptamethine group which may have a substituent. The definitions of other substituents are shown in the specification. According to the present invention, a photosensitive composition having high development latitude and storage stability, together with a positive type planographic printing plate for direct plate-making which can form an image with high sensitivity by using an infrared laser, are provided.
