A current collector protective glue includes a solvent and an adhesive. The solvent is selected from one or more of water, ethanol, NMP, acetone, and butanone. The adhesive is selected from one or more of cellulose, polyacrylic acid, styrene-butadiene rubber, styrene butadiene rubber, and nitrile rubber.

A rosin dispersion is a reaction product of, by dry weight based on total dry weight of the rosin dispersion, from 80% to 98% a rosin resin, and from 2% to 20% a dispersant. The rosin resin is processed by at least one method of a) modification, b) hydrogenation or disproportionation, and c) polymerization or esterification from raw material rosins. The dispersant is selected from C.sub.18-C.sub.32 aliphatic carboxylic acids, olefin (meth) acrylic acid copolymers, and other acid/anhydride modified polymers. A continuous process for preparing the rosin dispersion and an adhesive formulation comprising the rosin dispersion are also included.

The present invention pertains to a polarizing film having a transparent layer on at least one surface of a polarizer, wherein: the polarizer contains a polyvinyl alcohol-based resin and has a thickness of 15 μm or less; the transparent layer-side of the polarizer has a compatible layer thereon having compatibility with the transparent layer; and the thickness A of the polarizer and the thickness B of the compatible layer satisfy the general formula (100×B/A)≧1. This polarizing film has crack resistance and suppresses changes in the dimensions of the polarizer.
