    Abstract: PROBLEM TO BE SOLVED: To provide a coating composition to manufacture a lithographic printing plate showing high print durability and stability. SOLUTION: The coating composition is a radiation sensitive composition containing (a) at least one kind of quinone diazide compound and (b) at least one kind of copolymer containing units A, B, C and D. The units A, B, C are expressed by formulae (A), (B) and (C), respectively and the unit D is a unit having at least one free carboxyl group. In the formulae, R represents a hydrogen atom or a 1-4C alkyl group and R1 represents a 1-4C alkyl group.

    Abstract: A method for applying a matting layer to a radiation-sensitive layer of a printing plate precursor is disclosed. The method comprises: (a) providing a matting composition comprising a polymer and a solvent, wherein the matting composition has a solid content of more than 10% and no more than 50% by weight based on the total composition; and (b) spraying the matting composition on the radiation-sensitive layer using an electrostatically aided rotary atomizer having a bell speed of more than 10,000 rpm, wherein the distance between the bell and the radiation-sensitive layer to be coated is less than 30 cm. The printing plate precursor may be in the form of a moving web. The method of the present invention can be used for matting any kind of radiation-sensitive layer of conventional positive and negative working lithographic printing plate precursors.
