    摘要: ##STR1## By dehydrating indolines or their salts, the corresponding indoles having formula (I) are obtained. In the formula, R
    1 and R
    3 represent independently from each other hydrogen or alkyl groups with 1 to 4 C atoms, R
    2 stands for hydrogen, a methyl or a carboxyl group, R
    4 and R
    5 represent independently from each other hydrogen, amino groups, hydroxy groups, alkyl groups with 1 to 4 C atoms or alkoxy groups with 1 to 4 C atoms, or, in case R
    4 and R
    5 are bound to adjacent C atoms, both residues may also represent together an alkylene dioxy group with 1 to 4 C atoms. This process allows high yields of very pure indoles to be produced.

    摘要: The invention relates to the addition of dyes to aerobically curable adhesive compositions based on free-radically polymerizable compounds. The dyes serve as user-friendly indicators for monitoring the oxygen intake required to trigger the polymerization. The indicator dyes are especially suitable for aerobically adhesive compositions which contain activator systems for forming peroxides upon contact with air. Suitable dyes and indicators are those whose color change in aqueous solution lies within a pH range from 3.0 to 6.5.
