The present invention relates to a positive photosensitive polyimide composition that includes polyimide, a polyamic acid, and a photoactive compound. An organic insulating layer for organic light-emitting devices (OLED), which includes the positive photosensitive polyimide composition, may control a taper angle and outgassing, and has excellent adhesion in respects to a substrate, water repellent control ability, and storage stability and the like.

Positive photosensitive polyimide composition

The present invention relates to a novel cyclic olefin compound, a polymer including the cyclic olefin compound, a liquid crystal alignment film including the polymer, and a liquid crystal display device including the liquid crystal alignment film. Since the polymer includes the cyclic olefin compound as a main chain, the thermal stability is excellent and the photoreactive speed is high. Accordingly, the production time can be reduced, the production cost can be reduced, and the anchoring force of the liquid crystal can be increased because the alignment property is stabilized due to the curing.

The present invention provides an acrylic pressure-sensitive adhesive composition for a polarizing film comprising a) 100 parts by weight of a (meth)acrylic copolymer having a high molecular weight, which is copolymerized from a (meth)acrylic acid ester monomer and a vinylic and/or an acrylic monomer having a functional group capable of crosslinking with a multifunctional crosslinking agent and has a weight-average molecular weight of at least 1,000,000; b) 5-20 parts by weight of a (meth)acrylic copolymer having a low molecular weight, which comprises the same monomer of the main chain of a) the (meth)acrylic copolymer having a high molecular weight, has a weight-average molecular weight of 2,000-30,000 and comprises 0.01-1 monomer, per one molecule of the copolymer on average, having a functional group capable of reacting with the crosslinking agent of c); and c) 0.01-10 parts by weight of a multifunctional crosslinking agent.

Acrylic pressure-sensitive adhesive composition for polarizing film

The present invention relates to a novel silane coupling agent represented by Formula 1 below and a method for manufacturing the same. Because the compound has urethane and pyridine functional groups, it has superior storage stability and good adhesion property to a matrix resin having hydroxy groups, and thus can be used in a variety of applications. where each of Rand Ris hydrogen or C-Calkyl, a is an integer from 0 to 3, each of R, R, Rand Ris hydrogen, C-Calkyl, halogen, trifluoroalkyl or alkoxyalkyl and n is an integer from 1 to 3.

Silane coupling agent and method for manufacturing the same

The present invention relates to an acrylic pressure sensitive adhesive composition containing organic functional groups of urethane and pyridine, more precisely an acrylic pressure sensitive adhesive composition which has excellent removability owing to its low initial peel strength on glass and excellent long-term durability since the peel strength of the pressure sensitive adhesive composition onto glass is being increased under high temperature and high humidity. The present invention also relates to an acrylic pressure sensitive adhesive composition for a polarizer having excellent adhesive functions and durability, a polarizer and a LCD containing the same.

Acrylic pressure sensitive adhesive

Provided is an acrylic pressure-sensitive adhesive composition for a polarizing film comprising an acrylic copolymer copolymerized from (meth)acrylic ester monomers having different glass transition temperatures. The acrylic pressure-sensitive adhesive composition of the present invention can minimize the problem of light leakage due to shrinkage or expansion of a polarizing film attached to a liquid crystal display panel because it has very superior stress relaxation ability while maintaining superior major properties such as adhesion durability, cuttability, etc.
