There is provided a binder composition for a secondary battery, containing an organic solvent and a polymer binder dissolved in the organic solvent, in which the binder composition for a secondary battery contains 3 to 1.010.sup.5 ppm of a low-boiling point organic solvent (A) having a boiling point of lower than 120 C. in the binder composition. There are also provided a composition for a non-aqueous secondary battery, which contains the binder composition for a secondary battery as well as a sheet for an all-solid state secondary battery and an all-solid state secondary battery, which use the composition for a non-aqueous secondary battery, and manufacturing methods of these.

The invention provides a hydrophilizing agent which is to be added to a polymer having a large contact angle to produce a porous polymer film that has a small contact angle and that can maintain this small contact angle even after 168-hour contact with an aqueous sodium hypochlorite solution. The hydrophilizing agent contains a fluoropolymer having a contact angle of 50 or smaller and a weight reduction rate of 7% or lower.

The present invention provides a surface treatment film that is capable of imparting durability such as wear resistance, friction resistance, chemical resistance, heat resistance, and solvent resistance to the surfaces of various substrates, and that exhibits excellent adhesion to the surfaces of the substrates. The surface treatment film is provided on the surface of a substrate. The surface treatment film has a laminated structure that includes a polymer layer (i) disposed on the surface side of the substrate and a polymer layer (ii) disposed on the polymer layer (i). The polymer layer (i) contains a first polymer derived from a polymerization initiation group-containing polymer, such as a polyester having, in a side chain, a functional group represented by formula (1) wherein R.sub.1 represents a hydrogen atom, a methyl group, or the like, R.sub.2 represents a methyl group or the like, X represents a chlorine atom or the like, Y represents O or NH, and * shows a bonding position. The polymer layer (ii) contains a second polymer which contains a constituent unit derived from a monomer such as an aromatic vinyl-based monomer and which extends using the functional group represented by formula (i) as a polymerization initiation point.
