The invention relates to a composition intended for coating polymer films, making it possible to improve the adhesion between the film and a final coating, and to confer good barrier properties on the coated film. The coating composition comprises at least one acrylic and/or methacrylic polymer which has a gel content of at least 50% by weight, relative to the total weight of acrylic and/or methacryclic polymer, at least one crosslinking agent and at least one polyester comprising sulphonyloxy groups, which is water-soluble or water-dispersible.

Provided is an acrylic resin laminate film which has an excellent bonding property, resistance to water blushing, and an excellent external appearance. This acrylic resin laminate film is provided with: an acrylic resin layer (I) comprising an acrylic resin composition (A); and an acrylic resin layer (II) comprising a resin composition (B) that contains a reactive group-containing acrylic resin (B-1). (B) contains 10-100 mass % of (B-1), and 0-90 mass % of (B-2), which is an acrylic resin other than (B-1), with respect to 100 mass % of the total of (B-1), and (B-2), and further contains 0-50 parts by mass of (C), which is an additive other than (B-1), and (B-2), with respect to 100 parts by mass of the total of (B-1), and (B-2). (B-1) contains a monomer unit which has a substituent that reacts with an amino group, or a methylol group. The content of the monomer unit that has the reactive substituent is 3 mass % or more with respect to 100 mass % of (B).

An actinic ray-curable-type inkjet ink composition for 3D printing includes an acrylate monomer A capable of forming a homopolymer having a glass transition temperature of from 25 C. to 120 C.; an acrylate monomer B capable of forming a homopolymer having a glass transition temperature of 60 or higher and lower than 25 C.; a bifunctional acrylate oligomer C having a weight-average molecular weight of from 2,000 to 20,000; and an acylphosphine oxide compound, in which the mass content of bifunctional or higher-functional acrylate compounds is 15% by mass or less.

An ophthalmic device is disclosed that is a polymerization product of a monomeric mixture comprising: (a) a major amount of one or more non-silicone-containing hydrophilic monomers; (b) a crosslinking agent mixture comprising (i) one or more first crosslinking agents containing at least two ethylenically unsaturated reactive end groups, wherein the at least two ethylenically unsaturated reactive end groups are (meth)acrylate-containing reactive end groups and (ii) one or more second crosslinking agents containing at least two ethylenically unsaturated reactive end groups wherein at least one of the ethylenically unsaturated reactive end groups is a non-(meth)acrylate reactive end group, and (c) one or more hydrophilic polymers or copolymers comprising one or more hydrophilic units and a thio carbonyl thio fragment of a reversible addition fragmentation chain transfer (RAFT) agent wherein the ophthalmic device has an equilibrium water content of at least about 45 weight percent.

A polymer pipeline pig is provided for cleaning the interior of a pipeline capable of completely dissolving in a fluid including oil, water and/or gas over a time period of from 4 days to 24 days and over a temperature range of from 100 F. to 250 F. The polymer is selected from polylactic acid, polyglycolic acid, poly(lactic-co-glycolic acid) and combinations thereof The pipeline pig can be launched into the interior of the pipeline, allowed to move through the interior of the pipeline in a fluid including oil and water, and dissolved over a time period of from 4 days to 24 days and over a temperature range of from 100 F. to 250 F. Thus, no pig receiving facility is needed.

Disclosed herein are oral solid dosage forms comprising purified neutral acrylic polymer, methods of treating a dis ease or condition using the same and methods of preparing the same.

Structures for forming an optical feature and methods for forming the optical feature are disclosed. In some embodiments, the structure comprises a patterned layer comprising a pattern corresponding to the optical feature; a base layer; and an intermediate layer bonded to the patterned layer and the base layer.

The manufacturing device is provided with a first roller and a second roller for molding an uneven-thickness film. The first roller is provided with a truncated-cone-shaped portion and a disc-shaped portion, the diameter of the disc-shaped portion is larger than the diameter of a large-diameter face of the truncated-cone-shaped portion, and the second roller is provided with a column-shaped portion. A thick part is formed in a molded body of the uneven-thickness film between the truncated-cone-shaped portion of the first roller and the column-shaped portion of the second roller, and a thin connecting part is formed in the molded body between the disc-shaped portion of the first roller and the column-shaped portion of the second roller.

Provided is a water absorbent resin that is useful to sanitary materials such as a disposable diaper, a sanitary napkin, and a blood absorbent for medical use each having a higher liquid permeability and a higher water absorbing speed.
