Abstract:
The invention provides a colored photosensitive composition including: a coloring agent with a content of from 50% by weight to 80% by weight with respect to the total solid content of the composition; an oxime-based initiator with a content of from 5% by weight to 20% by weight with respect to the total solid content of the composition; and a resin containing at least one first structural unit represented by any one of the following formulae (1) to (3) containing an unsaturated double bond, and at least one second structural unit represented by the following formula (4) containing an acid group, wherein a ratio of the first structural unit to the second structural unit is 1.5 or more (molar ratio).
