The article contains a lipophilic cellulosic material, a tackifier, and a binder.

The present invention provides a carbon-fiber-reinforced composite material having excellent tackiness, excellent compatibility with epoxy resins, and excellent interfacial adhesion while being capable of achieving high mechanical strength, and a method for producing a carbon-fiber-reinforced composite material. Provided is a carbon-fiber-reinforced composite material containing: carbon fibers; an epoxy resin; a curing agent; and a polyvinyl acetal resin, the polyvinyl acetal resin including structural units represented by the following formula (1), each R.sup.1 in the formula (1) being an alkyl group having a carbon number of 1 or greater:

##STR00001##

wherein R.sup.1s may be the same as or different from each other.

Resin compositions, layers, and interlayers comprising two or more thermoplastic polymers and at least one RI balancing agent for adjusting the refractive index of at least one of the resins or layers is provided. Such compositions, layers, and interlayers exhibit enhanced optical properties while retaining other properties, such as impact resistance and acoustic performance.

Provided is an anti-fogging coated transparent article including an anti-fog film, the anti-fog film being a single-layer film containing a water-absorbent resin, a hydrophobic group, and a metal oxide component. The hydrophobic group is a chain or cyclic alkyl group having 1 to 30 carbon atoms, preferably a linear alkyl group having 6 to 14 carbon atoms, in which at least one hydrogen atom is optionally substituted by a fluorine atom. The hydrophobic group is bonded directly to a metal atom of the metal oxide component. The anti-fog film contains, for example, the metal oxide component in an amount of 0.01 to 60 parts by mass and the hydrophobic group in an amount of 0.05 to 10 parts by mass per 100 parts by mass of the water-absorbent resin. The water-absorbent resin is, for example, polyvinyl acetal.

Resin compositions, layers, and interlayers comprising two or more thermoplastic polymers and at least one RI balancing agent for adjusting the refractive index of at least one of the resins or layers is provided. Such compositions, layers, and interlayers exhibit enhanced optical properties while retaining other properties, such as impact resistance and acoustic performance.

There is provided an interlayer film for laminated glass with which the transparency can be enhanced. The interlayer film for laminated glass according to the present invention is obtained by mixing a first film material containing a first polyvinyl acetal resin and a second film material containing a second polyvinyl acetal resin and a plasticizer, and the absolute value of the difference between the content of the hydroxyl group of the first polyvinyl acetal resin and the content of the hydroxyl group of the second polyvinyl acetal resin contained together with the plasticizer in the second film material is less than or equal to 13% by mole.
