The present invention provided a fiber-treating liquid, modified fiber cloth, and process for producing the same. A modified fiber fabric obtainable by polymerizing a component (X) which is a water-soluble eggshell membrane powder, a component (A) which is a bifunctional monomer represented by the following formula (1), a component (B) which is a monomer containing any one of a hydroxyl group, carboxyl group, amino group, sulfonic acid group, and phosphoric acid group, and a component (C) which is a monomer containing at least one aziridine group, or a water-soluble polymer containing a polycarbodiimide group, polyethyleneimine group, or oxazoline group, on a fiber fabric, wherein R represents any one of and -C n H 2n - (n is an integer of 1 to 6) ; Z is a hydrogen atom or a methyl group;a and b are integers where 'a+b' is 0 to 50; x and y are integers where 'x+y' is 0 to 30; and 'a+b+x+y' is 10 or more.

Protein binding onto a polymeric surface is enhanced by treating the surface with an amine-bearing polymer like poly(ethylene imine). When used in ELISA, the treated surface improves the performance of the assay.

An electroless plating pretreatment agent that can retain stably Pd(II) over a long period of time in an organic solvent, an electroless plating method using the same that is capable of forming an electroless plated film having excellent adhesion, and an electroless plated object. The electroless plating pretreatment agent contains an organic palladium compound and a coordination compound having a functional group with a metal-capturing capability dissolved in an organic solvent, the coordination compound being selected from the group consisting of the imidazole analogs, polyethyleneamines, ethyleneimines and polyethyleneimines.

An environmentally friendly water-based paint capable of removing formaldehyde through reacting comprises 1 to 10 weight parts of ethylideneimine ketone, 30 to 45 weight parts of polymer emulsion, 0.5 to 2.0 weight parts of a film forming additive, 0.1 to 0.5 weight parts of an antifoaming agent, 20 to 40 weight parts of filling materials, 15 to 30 weight parts of distilled water and 2 to 5 parts of other additives. The preparation method of the environmentally friendly water-based paint comprises successively adding a wetting agent, a dispersant, parts of the antifoaming agent and the filling materials into the distilled water and then grinding to disperse to get slurry ; preparing a 30 % ethylideneimine ketone solution which is then added into the polymer emulsion; and successively adding the slurry, the film forming additive, the remaining antifoaming agent, a mildew preventor, an antifreeze, a levelling agent and a thickening agent into the polymer emulsion, adjusting a PH value to 8.0 to 9.5, and finally carrying out constant volume operation with the distilled water. The paint can effectively inhibit release of the formaldehyde in water-based paints, and has advantages of low production cost, simple process and suitability for popularizing.

The present invention provides organic-inorganic composite particles containing metal complexes, which have multiple needle-like structures on the surface and contain metal complexes; and a simple manufacturing method of the particles. This can be achieved by inducing a metal complex composed of a polymer having a linear polyethyleneimine skeleton and a metal ion to induce composite particles with a fine needle-like surface containing the metal complex inside the silica. Needle-shaped surface particles with multiple nanoscale needle-like structures on the surface of the particles. The needle-like structure of the resulting needle-shaped surface particles and the spatial structure of the particles can be controlled by changing the metal ion species and the metal complex support medium.

A coating agent for recording layer protection, characterized by comprising a carboxy-modified polyvinyl alcohol (A), a polyamide-polyamine epihalohydrin (B), and polyethyleneimine (C). Preferably, it is characterized in that the carboxy-modified polyvinyl alcohol (A) has a degree of saponification of 90 to 99.5 mol%. The coating agent for recording layer protection is highly effective in imparting water resistance to a recording medium. Also provided is a recording medium having high water resistance, characterized by being obtained by applying the coating agent for recording layer protection to a recording layer.
