This invention relates to rapid drying lacquers that are particularly useful for automotive OEM refinish applications. The lacquer includes a novel highly branched copolyester polyol. This invention is also directed to a process for producing coatings from the rapid drying lacquers. These lacquers are especially useful in providing for chip and humidity resistant coatings having improved adhesion.

Coatings comprising functionalized graphene sheets and at least one binder. In one embodiment, the coatings are electrically conductive.

The present invention refers to a method of manufacturing a micro patterned device. The method can comprise or consist of applying a light curable epoxy resin to a mold to obtain a curable resin filled mold. In a further step a polymeric film or an epoxy resin-coated glass is applied over the curable resin filled mold. Subsequently, the curable resin filled mold to which the polymeric film or the epoxy resin-coated glass is applied is irradiated to cure the resin. In another aspect the present invention refers to a micro patterned device obtained by a method described herein.

A resin film including a resin and an organic acid represented by the following formula (1), wherein the ratio of the organic acid to the resin is from 0.1 to 20% by mass:X-L-(R1)n   Formula (1)

The invention discloses a nano-cellulose liquid crystal membrane. The liquid crystal membrane is provided with rainbow stripes, and is prepared by the following steps of: adding water into cellulose nano-crystal powder to obtain cellulose nano-crystal suspension at the mass concentration of 0.1 to 10 percent; and putting the suspension into a culture vessel or spraying the suspension onto the surface of a medium, and heating and evaporating at the temperature of 20 to 80 DEG C for 1 to 12 hours to obtain the nano-cellulose liquid crystal membrane. The liquid crystal membrane can be used for decoration, anti-fake labels, color coatings and temperature sensors or optical verification equipment. For example, the membrane is sprayed on a substrate carrying data such as an identity card or a credit card so as to stop the attempt of faking by using a color copying machine.

Coatings are provided containing functionalized graphene sheets and at least one binder. In one embodiment, the coatings are electrically conductive.

A cellulose acylate film comprising at least one compound having a negative birefringence and satisfying 30 nm<Re<100 nm and 80 nm<Rth<300 nm is excellent in the wet heat durability of Re and Rth.

This invention relates to biopolymer-based compositions and biopolymer-based formed bodies such as film, sheet, capsule, casing or coating-film or spray thereof. In another embodiment, the invention relates to a process for producing a biopolymer-based starting material and biopolymer-based formed bodies such as cited above, for the manufacture of pharmaceutical, veterinary, food for cosmetic products.

Disclosed is a coating agent comprising a cellulose derivative, a 1,2-polybutadiene having an isocyanate group, a synthetic wax having a softening point of 100 to 150 DEG C, an aliphatic amide having a softening point of 60 to 170 DEG C and graphite. The coating agent has satisfactory levels of properties required for a coating agent for a rubbery elastic material, such as a sticking-preventing property, an adhesion-preventing property, a blocking-preventing property, and improved abrasion resistance. The coating agent can be used as a surface treatment agent for a vulcanized rubber, which does not cause adhesion upon compression at a high temperature or detachment of a coating film by friction / abrasion under a high surface pressure.

The present invention discloses a method of enabling the easy separation of labels, including wrap around labels and sleeve labels, particularly shrink sleeve labels, from containers during recycling through the use of a specially formulated coating to be applied in the seam area. The coatings ensure proper bonding, and shrink properties, of the labels, and have been designed to help de-bonding of the seam in a hot caustic wash step, or a solvent wash step. The method does not rely on floatation separation and therefore may be applied to any container / label material combination regardless of their specific gravity differences.

The invention discloses a super-oleophilicity hydrophobic material and a preparation method and application thereof. The preparation method for the hydrophobic material comprises the following steps: I, dissolving and activating microcrystalline cellulose by carbon-dioxide-based reversible ion liquid; II, preparing silane hydrolysate; III, adding cellulose solution to the hydrolysate, modifying the cellulose under the catalysis of ion liquid; IV, filtering, washing and drying the product, repeatedly using the solvent; and V, grinding solid and dispersing in ethanol solution. The dispersion liquid is sprayed to filter paper for oil-water filtering separation, the separation efficiency is more than 95%, and the organic pollutant in the water can be adsorbed. The normal sponge is soaked in the dispersion liquid for adsorbing the oil in the water. The surface contact angel of the filter paper prepared by the method is 165 degrees, and the rolling angle is smaller than 3 degrees. The whole raw material is green and environmental, and the preparation process is simple and efficient.
