It  is also preferable that the composition (Bl) as a  polymer compound used in the present invention further  have a repeating unit as described below (hereinafter, also  referred as "the other repeating unit") as a repeating unit  other than the repeating unit described above.  Examples of the polymerizable monomer for forming  these other repeating units include styrene, alkyl-substituted  styrene, alkoxy-substituted styrene, halogen-substituted sty› rene, O-alkylated styrene, O-acylated styrene, hydrogenated  hydroxystyrene, maleic anhydride, an acrylic acid derivative  (acrylic acid, acrylic acid ester, and the like), a methacrylic  acid derivative (methacrylic acid, methacrylic acid ester, and  the like), N-substituted maleimide, acrylonitrile, methacry› lonitrile, vinylnaphthalene, vinylanthracene, indene which  may have a substituent, and the like.  The compound (Bl) as a polymer compound may not  have these other repeating units, however in a case of having  the other repeating unit, the content of these other repeating  units in the compound (Bl) as a polymer compound is  generally from 1 to 30% by mo!, preferably from 1 to 20%  by mo! and more preferably from 2 to 10% by mo! with  respect to the total repeating units configuring the compound  (Bl) as a polymer compound.  The compound (Bl) as a polymer compound can be  synthesized by a  well-known radical  polymerization  method, a well-known anion polymerization method and a  well-known living radical polymerization method (an inifer› ter method, and the like). For example, in an anion polym› erization method, a vinyl monomer is dissolved in proper  organic solvent, a metallic compound (butyllithium, and the  like) is set as an initiator and a polymer can be obtained by  usually reacting under cooling conditions.  As the compound (Bl) as a polymer compound, a poly› phenol compound manufactured by the condensation reac› tion of an aromatic ketone or an aromatic aldehyde and a  compound having 1 to 3 phenolic hydroxyl groups (for  example, JP2008-145539A), a calixarene derivative (for  example, JP2004-18421A), a Noria derivative (for example,  JP2009-222920A),  and  a  polyphenol  derivative  (for  example, JP2008-94782A) can be also applied, and the  compound (B 1) may also be modified by a polymer reaction  to synthesize.  In addition, the compound (Bl) as a polymer compound  is preferably synthesized by modifying a polymer synthe› sized by a radical polymerization method or an anion  polymerization method, by a polymer reaction.  The weight average molecular weight of the compound  (Bl) as a polymer compound is preferably from 1,000 to  200,000, more preferably from 2,000 to 50,000, even more  preferably from 2,000 to 15,000.  The dispersity (the molecular weight distribution) (Mw/  Mn) of the compound (Bl) as a polymer compound is  preferably 2.0 or less, and from the viewpoint of improve- ment of sensitivity and resolution, is preferably from 1.0 to  1.80, more preferably from 1.0 to 1.60 and most preferably  from 1.0 to 1.20.  It  is preferable to use a living polymer› ization such as a living anionic polymerization since the  dispersity (the molecular weight distribution) of the obtained  polymer compound becomes uniform. The weight average  molecular weight and the dispersity of the compound (Bl)  as a polymer compound are defined as values that are  measured by GPC and expressed in terms of polystyrene. In  the specification, the weight average molecular weight (Mw)  and the number average molecular weight (Mn) of the  compound (Bl) may be obtained by using, for example, an  HLC-8120 (manufactured by Tosoh Corporation) using a  TSK gel Multipore HXL-M colunm (manufactured by  Tosoh Corporation, 7.8 mm IDx30.0 cm) as a colunm and  THF (tetrahydrofuran) as an eluent.  The addition amount of the compound (Bl) with respect  to the composition in the present invention is preferably  from 30 to 95% by mass, more preferably from 40 to 90%  by mass and particularly preferably 50 to 85% by mass, with  respect to the total solid contents of the composition.  Specific examples of the compound (Bl) are shown  below, but the present invention is not limited thereto.
