Abstract

Provided is a positive photoresist composition excellent in terms of heat resistance. A radically curable compound is represented by a general formula (1) below (where R 1 , R 2 , and R 3 each independently represent an alkyl group having 1 to 8 carbon atoms; m and n each independently represent an integer of 1 to 4; p represents an integer of 0 to 4; X, Y, and Z each independently represent an acryloyloxy group, a methacryloyloxy group, or a hydroxy group, and at least one of X, Y, and Z represents an acryloyloxy group or a methacryloyloxy group; and t represents 1 or 2).

First claim

1 - 4 . (canceled)

5 . A method for producing a radically curable compound, comprising causing polycondensation between an alkyl-substituted phenol (a1) and an aromatic aldehyde (a2) having a hydroxy group on a benzene ring to prepare a polycondensate (A) represented by a general formula (3) below

(where R 1 , R 2 , and R 3 each independently represent an alkyl group having 1 to 8 carbon atoms; m and n each independently represent an integer of 1 to 4; p represents an integer of 0 to 4; and s represents 1 or 2); and
subsequently causing a reaction between the polycondensate and a (meth)acrylic acid halide (B).

6 . The method for producing a radically curable compound according to claim 5 , wherein the alkyl-substituted phenol (a1) is 2,5-xylenol or 2,6-xylenol.

7 . The method for producing a radically curable compound according to claim 5 , wherein the aromatic aldehyde (a2) having a hydroxy group on a benzene ring is a 4-hydroxybenzaldehyde.

8 . The method for producing a radically curable compound according to claim 5 , comprising a step 1 of causing polycondensation between the alkyl-substituted phenol (a1) and the aromatic aldehyde (a2) having a hydroxy group on a benzene ring in the presence of an acid catalyst to prepare a crude product containing the polycondensate (A) in a reaction solution; a step 2 of collecting from the reaction solution the polycondensate (A) prepared in the step 1; and a step 3 of causing the reaction between the polycondensate (A) isolated in the step 2 and the (meth)acrylic acid halide (B) in the presence of a base.

9 . A radically curable compound obtained by the production method according to claim 5 .

10 - 12 . (canceled)

13 . A radically curable compound obtained by the production method according to claim 6 .

14 . A radically curable compound obtained by the production method according to claim 7 .

15 . A radically curable compound obtained by the production method according to claim 8 .

16 . A radically curable composition comprising the radically curable compound according to claim 9 .

17 . A radically curable composition comprising the radically curable compound according to claim 13 .

18 . A radically curable composition comprising the radically curable compound according to claim 14 .

19 . A radically curable composition comprising the radically curable compound according to claim 15 .
