Image recording material

1. A negative-type image recording material comprising:

a support having a rear surface; and

an image recording layer disposed on the support, having a front surface, and including (A) a radical-generating agent, (B) a radically polymerizable compound, and (D) a compound represented by the following formula (1):

R 1 −X  (1)

wherein R 1 represents an optionally substituted hydrocarbon group having a total of 8 to 32 carbon atoms; and X represents CO—Y—R 2 , Y—CO—R 2 , NH—CO—Y—R 2 , O—CO—NH—R 2 , NH—CO—NH—R 2 , SO 2 —Y—R 2 , Y—SO 2 —R 2 , O—SO 2 —R 2 , CO—O—CO—R 2 , or Y—R 3 in which Y represents O, S, NR 4 or a single bond, but if X is Y—R 3 , then Y is not a single bond, and R 2 , R 3 and R 4 each independently represent a hydrogen atom or an optionally substituted hydrocarbon group having a total of not more than 20 carbon atoms, wherein the compound (D) has a radically polymerizable functional group and wherein said image recording layer further comprises a (C) light absorbent which is a dye or pigment having maximum absorption at a wavelength from 760 to 1200 nm.

2. The negative-type image recording material according to claim 1 , wherein said (A) radical-generating agent is an onium salt selected from the group consisting of iodonium salts, diazonium salts, and sulfonium salts.

3. The negative-type image recording material according to claim 1 , wherein said (B) radically polymerizable compound is a radically polymerizable compound having at least one ethylenically unsaturated double bond.

4. The negative-type image recording material according to claim 1 , wherein said image recording layer further comprises a binder polymer.

5. The negative-type image recording material according to claim 2 , wherein said onium salt has a maximum absorption at a wavelength of 400 nm or less.

6. The negative-type image recording material according to claim 2 , wherein said onium salt is contained in an amount of 0.1 to 50 wt % with respect to total solid content of a coating solution for the image recording layer.

7. The negative-type image recording material according to claim 1 wherein, if the front surface of a portion of the image recording material is in contact with the rear surface of a portion of the image recording material, a static friction coefficient between the front surface and the rear surface is less than 0.50.

8. A negative-type image recording material comprising:

a support having a rear surface; and

an image recording layer disposed on the support, having a front surface, and including (A) a radical-generating agent, (B) a radically polymerizable compound, and (D) a compound represented by the following formula (1):

R 1 −X  (1)

wherein R 1 represents an optionally substituted hydrocarbon group having a total of 8 to 32 carbon atoms; and X represents CO—Y—R 2 , Y—CO—R 2 , NH—CO—Y—R 2 , O—CO—NH—R 2 , NH—CO—NH—R 2 , SO 2 —Y—R 2 , Y—SO 2 —R 2 , O—SO 2 —R 2 , CO—O—CO—R 2 , or Y—R 3 in which Y represents O, S, NR 4 or a single bond, but if X is Y—R 3 , then Y is not a single bond, and R 2 , R 3 and R 4 each independently represent a hydrogen atom or an optionally substituted hydrocarbon group having a total of not more than 20 carbon atoms, wherein the compound (D) has a radically polymerizable functional group, and

the presence of compound (D) makes a static friction coefficient between the front surface and the rear surface less than 0.50.

9. The negative-type image recording material of claim 1 , wherein R 1 represents a linear alkyl group, a branched alkyl group or an aryl group.
