    摘要： A producing process of amino resin crosslinked particles includes the step of curing an emulsion of an amino resin precursor and an emulsifier in the presence of a catalyst, the amino resin precursor being a product of a reaction of an amino compound with formaldehyde, so as to prepare amino resin particles, the step of neutralizing the suspension of the amino resin particles after the curing step, and the step of heating the suspension in a temperature range of 130°C to 230°C after the neutralizing step. The amino resin crosslinked particles thus prepared by the condensation of the amino compound and formaldehyde generate formaldehyde in an amount of not more than 1000 ppm in a pyrolysis test and have a characteristic that a Hunter whiteness is not less than 85 percent.

    摘要： A thermal transfer inked ribbon having good transfer property and offering vivid and highly durable transfer image. In constituting a thermal transfer inked ribbon (1) by using a hot-melt resin binder material as a main component and by forming an ink layer (13), low-lubrication fine particles are contained in the ink layer (13), the low-lubrication fine particles without being softened at a temperature at which the binder material softens. Since the hot-melt resin is used, the transfer image features enhanced durability. Besides, since fine particles are contained, the thermal transfer inked ribbon can be favorably cut. The fine particles have low lubrication and suppress slippage. The low-lubrication fine particles have an average particle diameter of 0.3-3.0 mu m, and are made of benzoguanamine-formaldehyde condensate resin, melamine-formaldehyde condensate resin, benzoguanamine-melamine-formaldehyde condensate resin, or polytetrafluoroethylene resin. The ink layer (13) contains 10-60 wt.% or preferably 20-50 wt.% such resin.

    摘要： A metal-containing polyaledehyde microsphere composed of a polyaldehyde microsphere to which a transition metal, e.g. Au, Ag, Pt, Pd, Tc, Fe, Ni or Co, is bound may be obtained in accordance with this invention. The polyaldehyde, e.g. polyacrolein or polyglutaraldehyde, may be encapsulated in agarose, and the mocrosphere may be radioactive or magnetic. The microphere may additionally have a compound having at least one amine group, e.g. a drug, antibody, antigen, enzyme or other protein, bound to its surface.
    In one embodiment a transition metal is bound to a polyaldehyde microsphere by contacting the polyaldehyde microsphere with a suitable amount of an appropriate salt or acid of the transition metal under suitable conditions so as to cause the salt or acid to be reduced to a lower valence state and to bind to the microsphere. Some salts or acids may thus be reduced to the elemental state; others are further reduced with an appropriate reducing agent.
    In another embodiment, a transition metal in elemental form is bound to a polyaldehyde microsphere by contacting the polyaldehyde microsphere with a suitable amount of a compound capable of complexing with a salt or acid of the transition metal under suitable conditions permitting binding of the compound to the microsphere, contacting the compound with an appropriate amount of an appropriate salt or acid of a transition metal under appropriate conditions permitting the compound to bind to the salt or acid, and reducing the salt or acid to the corresponding elemental metal by contacting it under effective reducing conditions and for a sufficient period of time with a sufficient amount of an effective reducing agent. The metal-containing microsphere of this invention is useful for such applications as cell labeling, cell separation, diagnostic methods, catalysis and coating methods.
