Abstract:
A hybrid pressure sensitive adhesive (PSA) composition includes (i) a solvent phase comprising a first acrylic PSA dissolved in an organic solvent, an alcohol, and optionally water; and (ii) an emulsion phase comprising a second, emulsified acrylic PSA. In another aspect, a metalized film laminate includes a metalized film layer, a hybrid PSA layer, and an ink-containing polymeric film layer. The two-phase hybrid PSA system effectively addresses both metal tear and ink pick problems associated with conventional metalized film laminates.

The present invention is to provide: a non-aqueous dispersant which is excellent in dispersibility and dispersion stability and able to form a resin layer with excellent hydrolysis resistance; a color material dispersion liquid containing the non-aqueous dispersant; and a color resin composition containing the non-aqueous dispersant.Disclosed is a non-aqueous dispersant which is a polymer comprising at least one constitutional unit represented by the following general formula (I), wherein at least part of nitrogen sites of the constitutional units each form a salt with an acidic organophosphorous compound comprising one or more selected from the group consisting of organic phosphonic acid monoester compounds resulting from addition of a monofunctional epoxy compound or monofunctional oxetane compound to an organic phosphonic acid: Symbols shown in the general formula (I) are described in the Description.
Abstract:
Improved methods for preparing sulfonated block polymers with acyl sulfates in non-halogenated aliphatic solvents are provided. The methods include the sulfonation of a precursor block polymer with an acyl sulfate in a reaction mixture further comprising at least one non-halogenated aliphatic solvent to form a sulfonated block polymer, wherein the initial concentration of the precursor block polymer is in the range of from about 0.1 wt % to a concentration that is below the limiting concentration of the precursor block polymer based on the total weight of the reaction mixture. A sulfonation degree of greater than about 1.0 milliequivalent sulfonic acid per gram sulfonated block polymer can be achieved substantially free of polymer precipitation and free of disabling gelation.

Abstract:
It is possible to provide polyimide powder which has an average size of 25 μm or less and is free from metal impurities which would otherwise be produced due to abrasion of a machine used for mechanical milling.The polyimide powder is an aggregate of fine particles produced through precipitation of polyimide dissolved in a treatment solution containing a basic substance. A residual amount of alkali metal derived from the basic substance contained in the treatment solution is 1% or less of a total amount of the polyimide powder. It is possible to reduce bad effects due to an alkali metal residue and to prevent decomposition of polyimide by the alkali metal residue.
