In addition, in the present invention, the compound (PA) may be appropriately selected other than the compound that generates the compound represented by Formula (PA-1 ). For example, as an ionic compound, the compound having a proton acceptor moiety may be used in a cation moiety. More specifically, the compound represented by the follow› ing Formula (7) will be exemplified.

In the formula, A represents a sulfur atom or an iodine 50 atom. 

M represents 1 or 2, and n represents 1 or 2. However, when A is a sulfur atom, m+n=3, and when A is an iodine atom, m+n=2. 

R represents an aryl group. 

RN represents an aryl group substituted with proton› accepting functional group. 

x- represents a counter anion. 

Specific examples of x- may include the same as x- in t Formula (ZI). 

Specific examples of the aryl group of R and RN prefer› ably include a phenyl group. 

Specific examples of the proton-accepting functional group that RN has are the same as the proton-accepting functional group described in Formula (PA-1). 

In the composition of the present invention, the blending ratio of the compound (PA) in the entire composition is 

preferably 0.1 to 10% by mass, and more preferably 1 to 8% by mass, based on the total solid content of the composition. 

(6) Guanidine Compound 

The composition of the present invention may further have the guanidine compound having the structure repre› sented by the following Formula.

Since the guanidine compound in which a positive charge of a conjugate acid is dispersed and stabilized by three kinds of nitrogen, it shows a strong basicity. 

As the basicity of the guanidine compound (A) of the present invention, pKa of the conjugate acid is preferably 6.0 or more, and more preferably 7 .0 to 20.0 in the view that the neutralizing reactivity with an acid is high and the roughness characteristics are excellent, and more preferably 8.0 to 16.0. 

Because of such a strong basicity, the diffusion of an acid is suppressed, which can contribute to the formation of good pattern shape. 

In addition, here "pKa" indicates pKa in an aqueous solution, and, for example, indicates those described in chemical handbook (II) (Revised Fourth Edition, 1993, the Chemical Society of Japan, Maruzen Co. Ltd.). The lower the value indicates, the larger the acid strength is. pKa in an aqueous solution can be specifically measured by measuring
