Abstract: An organic solution of a composition consisting essentially of 100 parts of an indium compound represented by the formulaIn(X).sub.l (Y).sub.mwherein X denotes a chelate ring formed by .beta.-diketones, esters of .beta.-ketoacids or the like, Y denotes an alkoxide formed by aliphatic alcohols or the like, and l and m denote an integer which is either 1 or 2 having the relationship of l+m=3, and from 5 to 20 parts of a tin compound represented by the formulaSn(X').sub.2 or Sn(Y')m'wherein X' denotes a chelate ring formed by .beta.-diketones or esters of .beta.-ketoacids, Y' denotes an alkoxide formed by aliphatic alcohols, and m' denotes 2 or 4, is suitable for deposition of transparent, hardened and low resistivity film coatings of tin-doped indium oxide on a substrate by dipcoating.

Abstract: As an absorbent for chlorine, heavy metals or heavy metallic compounds, a resin prepared by reacting polyisocyanate with at least one compound selected from the group consisting of polyols and functional monomers which have at least 2 active hydrogen atoms and at least one functional group selected from the group consisting of ##EQU1## >NH and --N=, such that the ratio of the total active hydrogen atom number in the polyol and functional monomer to the total isocyanate group number in the polyisocyanate is 0.8 to 5.0.

Abstract: An adsorbent process for heavy metals or heavy metallic compounds, which comprises utilizing a resin prepared by a reaction between aldehydes, dithiocarbamate compounds and aromatic compounds having at least one radical selected from the group consisting of --OH, --SH, --COOH and --COOMe (wherein Me represents sodium, potasium, NH.sub.4 or calcium).
