Thermally shrinkable laminate film for deep drawing, packaged article, and method for packaging of cheese
The invention has for its object to provide a heat-shrinkable laminated film for deep drawing, which has an increased carbon dioxide transmission rate (CO.sub.2TR) and an enhanced ratio (CO.sub.2TR/O.sub.2TR) of carbon dioxide transmission rate-to-oxygen transmission rate (O.sub.2TR), and is less susceptible to pinholes. In the inventive heat-shrinkable laminated film for deep drawing, a polyamide resin composition layer (a) containing a polyamide resin mixture comprising 60 to 95% by mass of an aliphatic polyamide resin (A) and 5 to 40% by mass of a polyamide base resin (B) having a heat of crystalline fusion of 5 to 40 J/g is laminated onto a heat-sealing resin layer (a) containing a polyolefin resin via an adhesive resin layer (b).
Sliding member and process for producing the same
Object: To provide a sliding member with a low friction coefficient in which, when fine dents are formed in a surface of the sliding member by dimpling using a laser, no hard raised portions are generated, and which does not damage a mating member; and to provide a process for producing the sliding member. Solution Means: A sliding member comprising a polyamide resin and 10 to 50 wt % of a fibrous filler selected from the group consisting of carbon fibers, aramid fibers, and whiskers, and having fine dents formed in a sliding surface thereof by dimpling using a laser; and a process for producing a sliding member comprising adding 10 to 50 wt % of a fibrous filler selected from the group consisting of carbon fibers, aramid fibers, and whiskers to a polyamide resin, and forming fine dents in a sliding surface of the sliding member by dimpling using a laser.

Article comprising light absorbent composition to mask visual haze and related method
A transparent article includes a continuous polyester matrix having at least one incompatible filler dispersed therein. The incompatible filler provides domains in the polyester matrix, each domain having a particular dimension, thus providing a range of dimensions for the domains in the article. To create haze, the dimensions are within the range of from about 380 nm to about 720 nm. Once the range of dimensions is determined, a light absorbent composition can be found which absorbs light at a range of wavelengths that at least substantially covers the range of dimensions of the domains. In doing so, it has been found that the haze of the article can be substantially masked. Method for producing the article and for masking the haze are also provided.

Process for the preparation of multifunctional polycarbodiimides which are used as crosslinking agents
A process for the preparation of multifunctional polycarbodiimides, which are used as crosslinking agents, in which the polycarbodiimide is prepared by reacting mono- and polyisocyanates in the presence of a mono- or polyisocyanate that contains one or multiple additional reactive functional groups and in the presence of a carbodiimide catalyst, and thereafter terminating or chain extending the polycarbodiimide chain. Between 0 and 10% of an organic solvent and/or between 0 and 30% of a plasticizer and/or between 0 and 30% of a surface active component is added to the product during, before or after the polycarbodiimide forming reaction and/or the capping reaction and/or the chain extending reaction. Further, the invention relates to a coating mixture in which the polycarbodiimide is used as crosslinking agent and to the cured material obtained with the coating mixture.

Thermoplastic resin composition
Provided is a thermoplastic resin composition in which a modified rubber excellent in low temperature resistance is dispersedly added in a polyamide resin matrix to improve the low temperature resistance (cyclic fatigue resistance) of the polyamide resin, the composition maintaining its fluidity even at a high content of modified rubber, thus allowing film formation, and exhibiting excellent low temperature resistance. The thermoplastic resin composition includes a polyamide resin (A) and a modified rubber (B) having an acid anhydride group or an epoxy group and is characterized in that the modified rubber (B) having an acid anhydride group or an epoxy group is modified with a hydrogen bonding compound (C) having a functional group reacting with an acid anhydride group or an epoxy group and a functional group capable of hydrogen bonding with an amide bond or a hydroxyl group. In addition, the polyamide resin (A) is preferably modified with a compound capable of bonding to a terminal amino group of the polyamide resin. The thermoplastic resin composition is suitably used for production of tires, hoses and the like.
