Abstract: Gallium contained in a solution, especially a strongly basic aqueous solution can be effectively recovered by contacting the solution with a chelate resin having (A) .dbd.NOH group and (B) functional group capable of forming a chelate bond with said functional group (A) through gallium or a chelate resin having metal salt of said functional group to adsorb gallium to the resin.

Abstract: Coated formed materials of plastics or glass having improved anti-scratching and anti-fogging properties, are produced by applying to the surface of the formed material an undercoating material comprising (a) a mixture of methylolmelamine in which all or a part of the methylol groups are alkyletherified, and a polyhydric alcohol having a molecular weight of 1,500 or less which may contain an ethylene oxide or propylene oxide chain, or a pre-condensate thereof, (b) a mixture of a monomer having a unit of the formula (I), ##STR1## wherein R.sub.1 and R.sub.
