摘要:
A method is provided for forming an adherent image, such as a design, print, or decoration, on a substrate by applying a fusible pigmented polyolefin powder in a selected pattern to a hot surface of a polyolefin substrate, and fusing the particles of the powder to each other and to the surface to form the image on cooling.
摘要:
A process for sensitising or dyeing a film of polyethylene terephthalate which involves applying to the film a liquid medium containing ingredients of a one-component diazotype material or a dyestuff and also a halogenated acetic acid, a halogenated propionic acid or a fully halogenated derivative of acetaldehyde and heating to effect evaporation of the medium.
摘要:
A method and apparatus for decorating the nails of hands and feet is provided in the form of a decal assembly which includes a generally ovoid decal on a carrier strip, said decal carrying a design and adapted to cover the surface of the nail, an adhesive material temporarily holding the decal on said strip and adapted to be released therefrom and transferred adherently to the nail and a nail polish solvent resistant clear layer or coating on said ovoid decal opposite the carrier strip. The nail is coated with a nail lacquer prior to receiving the decal and then the transferred decal and the nail are coated with a clear transparent nail lacquer.
摘要:
A temporary carrier of paper, aluminium, regenerated cellulose, polyester terephthalate or polyolefine sheets, or laminates thereof, which carries on one of its surfaces a detachable film of pigmented vinyl resins with a preferably multi-coloured pattern or design, an underlying layer consisting of a mixture of nitrocellulose and an aminoplast or of nitrocellulose and an alkyd resin, wherein there is present on the detachable film a thin adhesive layer containing resins which are soluble in organic solvents and possess a pendulum hardness according to Konig (DIN 53 157) of at least 85 seconds, a process for the manufacture of said temporary carrier, and a process for the dry transfer of all desired design on a definitive A.B.S., polycarbonate, polyvinyl chloride or polystyrene surface, which comprises overlaying said temporary carrier on the surface required to be decorated, on or after the manufacture of the latter, subsequently exposing it to the action of heat, pressure or both, and detaching the temporary support from the decorated surface, optionally after cooling.
摘要:
A METHOD FOR PRODUCING THREE-DIMENSIONAL FORMS OF FOAM PLASTIC WHEREIN A HEAT-RESISTANT MASK IS APPLIED TO A SURFACE OF A HEAT-COLLAPSIBLE FOAM BODY, AND THE MASKBEARING BODY IS EXPOSED TO A SPACED SOURCE OF HEAT ENERGY FOR A TIME SUFFICIENT TO COLLAPSE THE UNMASKED AREAS OF THE FOAM.
摘要:
Polyethylene film is caused to degrade in a predetermined pattern by the printing of the pattern on the surface of the film using printing ink containing a degradation promoter such as ultraviolet sensitizers, oxidation promoters, or embrittling agents.
摘要:
A process is provided for applying printed matter to plastic substrates by coating the substrate with a composition capable of generating aluminum phosphate. A complex aluminum phosphate having at least 1 chemically-bound molecule of an hydroxy compound ROH where R is hydrogen or an organic group is preferred. The coating is heated to provide at least a partially cured layer of aluminum phosphate and the inked pattern is applied thereto.
摘要:
The receptivity of thermoplastics, for example, polyethylene and polypropylene, to coatings is improved by incorporating into the thermoplastic a finely divided, particulate inorganic filler and an organic resin having a softening point lower than the thermoplastic, a softening range of about 30* to 100* C and capable of being degraded by conventional oxidizing pretreatment.
摘要:
Apparatus for the continuous process for the preparation of synthetic paper by treatment of a polymer film to produce an opaque printable surface the process including treating the surface with a swelling agent followed by a coagulating agent with intermediate treatment in one or more baths containing adjustable quantities of swelling and coagulating agents, said baths being provided with overflow means leading to the preceding bath to provide adjustment for changes caused by carry-over from one bath to another by the advancing film.
摘要:
A laminated article in which a composition containing polyvinyl chloride, polyvinyl acetate and polyvinyl alcohol is interposed between a vinyl skin and the printing on the surface of a vinyl core to improve the adhesion between the skin and the printing ink. A method of laminating is also claimed.
