Disclosed are a composite resin composition containing a thermosetting resin including an unsaturated polyester resin and a saturated polyester resin, a filler, and a processability-improving agent. More particularly, disclosed are a composite resin composition that is capable of providing a molded article having a lower specific gravity and improved surface quality compared to a conventional molded article by improving the compatibility and impregnability of a thermosetting resin and a filler using a processability-improving agent, and a molded article manufactured using the same.

Provided is a recycling method of a polyester cotton blended fabric, including the following steps. A dye-containing polyester cotton blended fabric is put into an acidic aqueous solution containing an oxidizing agent for heating and soaking, so as to degrade the cotton in the polyester cotton blended fabric into powder, and decolorization is performed at the same time to remove the dye. After that, a polyester fabric and cotton powder are obtained by double filtration.

A resin composition and method for installing a pipe liner that allows the liner to be fully wet out with a resin and activator and stored for a period of up to six months prior to installation and curing. A method of lining a pipe with a delayed curing resin composition is also provided that includes fully wetting out a liner with a blended two part epoxy composition such that the liner can be transported in a wet out fashion, placed in a pipe to be lined and repositioned as needed without concern for the resin composition to begin curing.

A laminate, including a substrate having a microstructure on a surface thereof; and a coating layer formed on the substrate and encapsulating the microstructure of the substrate. A glass transition temperature T.sub.1 of the substrate is higher than a glass transition temperature T.sub.2 of the coating layer. A method of producing an ophthalmic lens, including deforming the laminate into a shape of the ophthalmic lens by applying heat and/or pressure at a temperature of lower than T.sub.1.

A frame is injection molded onto a group of panels to form a container. The panels extend at least partially around, and at least partially define, a cavity of the container.

A method for joining two objects by anchoring an insert portion provided on a first object in an opening provided on a second object. The anchorage is achieved by liquefaction of a thermoplastic material and interpenetration of the liquefied material and a penetrable material, the two materials being arranged on opposite surfaces of the insert portion and the wall of the opening. During the step of inserting the insert portion in the opening and/or during anchorage a clamping force is applied to opposing surfaces of the second object to prevent the second object from cracking or bulging.

An object of the present invention is to provide a thin volume hologram sheet to be embedded sufficiently resistant to a mechanical stress such as a stress including a tensile stress, a shear stress and a compression stress at the time of processing even under a heating condition, a forgery prevention paper and a card using the same. The object is achieved by providing a volume hologram sheet to be embedded comprising a volume hologram layer, and a substrate disposed only on one side surface of the volume hologram layer using an adhesion means, wherein a peeling strength of the volume hologram layer and the substrate is 25 gf/25 mm or more.
