In the present invention, a compound represented by the following formula (0) is used. □ (In the formula (0), RY is a linear, branched or cyclic alkyl group having a carbon number of 1 to 30 or an aryl group having a carbon number of 6 to 30, and RZ is an N value of a carbon number of 1 to 60. a radical or a single bond, each of which is independently an alkyl group having 1 to 30 carbon atoms which may have a substituent, an aryl group having 6 to 40 carbon atoms which may have a substituent, and 2 to 30 carbon atoms which may have a substituent. An alkenyl group, a group having an alkoxy group having 1 to 30 carbon atoms, a halogen atom, a nitro group, an amine group, a cyano group, a decyl group, a hydroxyl group or a hydroxyl group which may have a substituent, which is substituted with an acid dissociable group, The alkyl group, the aforementioned alkenyl group and the aryl group may contain an ether bond, a ketone bond or an ester bond. Here, at least one of RT is a group in which a hydrogen atom of a hydroxyl group or a hydroxyl group is substituted with an acid dissociable group, and X represents oxygen. An atom, a sulfur atom or no cross-linking, m is independently an integer from 0 to 9, where at least one of m is an integer from 1 to 9, and N is an integer from 1 to 4, where N is 2 or more. In the case of integers, the structural formulas in N of [ ] may be the same or different, and r is independently an integer of 0 to 2). |
