Abstract:
To provide a hard coating composition which forms a hard coat layer that has high visibility and good hardness, while having stretchability. To provide a technique which is capable of effectively preventing blocking phenomenon in a layered product such as a resin film without adversely affecting the visibility. The present invention provides a hard coating composition which contains (A) a phenolic novolac acrylate that has two or more acrylate groups and (B) an aromatic group-containing mono or poly(meth)acrylate compound that contains 1-2 mol of an alkylene oxide structure having two or three carbon atoms in each molecule. This hard coating composition contains 60-85 parts by mass of the phenolic novolac acrylate (A) and 15-30 parts by mass of the (meth)acrylate (B) per 100 parts by mass of the resin component contained in the hard coating composition.
Abstract:
The present document describes a composition for the pretreatment of surfaces, which comprises plasticizers, degassers, pH adjusting agents, pigments, a phenol formaldehyde resin based adhesive, process of making the same and method of using the same.
Abstract:
Storage stable polyhydroxylated aromatic ether adducts of polyalkylene oxide are described. Reactive compositions are formed by combining an ether adduct with an aldehyde, optionally further adding a phenolic-aldehyde prepolymer. The reactive compositions are cured by removing water, by acidification, or both. The cured compositions sorb solvated compounds from environments containing water. The cured compositions are also useful for pre-loading with compounds that are subsequently released at a controlled rate into environments containing water.
Abstract:
There is provided a coating material for coating at least a part of an inner wall of a pipe for transporting oil and or gas mined from underground. It contains an acid curing agent and an acid curable resin to be cured by the acid curing agent. The coating material passes through the pipe for transporting the oil and/or gas mined from the underground to coat at least a part of the inner wall of the pipe with a cured product of the acid curable resin. It is possible to provide the coating material for coating the inner wall of the pipe for transporting the oil and/or gas mined from the underground to prevent corrosion of the inner wall of the pipe by a high anti-corrosion effect thereof. There is also provided a method for coating the inner wall of the pipe with the cured product of the coating material.
Abstract:
A composition for forming a resist underlayer film includes (A) a compound. The compound (A) includes a group represented by formula (1). R represents a monovalent organic group having 1 to 30 carbon atoms. The monovalent organic group represented by R does not include an oxygen atom at an end of the side adjacent the sulfur atom. * represents a bonding hand. The compound (A) preferably includes a ring which is an aromatic ring, a heteroaromatic ring, or a combination thereof. The bonding hand denoted by * in the group represented by the formula (1) is preferably linked directly or via an oxygen atom to the ring.
Abstract:
A positive resist composition comprising an organosiloxane-modified novolak resin, a photosensitive agent, and an organic solvent is provided, the resin comprising structural units having formula (1) wherein R1 is an organosiloxy group, and R2 is hydrogen or alkyl. The composition is photosensitive, turns alkali soluble in the exposed region, eliminates any film thickness loss after development, and displays improved resistance to electrolytic plating and O2 dry etching.
