Cationic phthalocyanine dyes of the formula ##STR1## where Pc is an (m+n+p)-valent phthalocyanine radical, R.sup.1 is H or alkyl, R.sup.2 and R.sup.3 independently of one another are alkyl, hydroxyalkyl, cycloalkyl, benzyl, phenyl or tolyl, or ##STR2## is pyrrolidinyl, imidazolyl, 2-ethyl-4-methylimidazolyl, morpholinyl, piperazinyl or N'-alkylpiperazinyl, or is ##STR3## R.sup.4 is H or methyl, R.sup.5 is alkyl, hydroxyalkyl or benzyl, X.sup..sym. is one equivalent of an anion, M.sup..crclbar. is one equivalent of a cation, z is 1 or 2, p is 0 or 1, m is 0 or 1 and n is from 1 to 4, and 1<(m+n)<4, are readily or highly soluble in water and very substantive on paper, and accordingly are particularly suitable for dyeing and printing paper. Paper dyed with (I) has very good bleeding fastness, and a colorless effluent is obtained when paper is wet-end dyed.
