Abstract
Provided is a planographic printing plate precursor including: a support; and an image recording layer formed on the support, in which a region on the plate surface on the image recording layer side from an end portion of the planographic printing plate precursor to a portion inside the end portion by 5 mm contains a polymer containing a functional group represented by the following Formula (A), and the content of the polymer per unit area in the region is greater than the content of the polymer per unit area in a region other than the above-described region by an amount of 10 mg/m2 or greater. —Si(X)m(R3)n (A)
Claims20
A planographic printing plate precursor comprising:
- a support;
- and
- an image recording layer formed on the support,
- wherein a region on a plate surface of the planographic printing plate precursor on the image recording layer side from an end portion of the planographic printing plate precursor to a portion inside the end portion by 5 mm contains a polymer containing a functional group represented by the following Formula (A), and
- the content of the polymer per unit area in the region is greater than the content of the polymer per unit area in a region other than the above-described region by an amount of 10 mg/m2 or greater,
- —Si(X)m(R3)n (A)
- in Formula (A), X represents an alkoxy group, an aryloxy group, an acyloxy group, a hydrogen atom, or a hydroxyl group, R3 represents a hydrocarbon group, m represents an integer of 1 to 3, and in a case where m represents 2 or 3, X's may be the same as or different from each other, n represents an integer of 0 to 2, and in a case where n represents 2, R3's may be the same as or different from each other, and m+n is 3.
