Curing agent for curing epoxy resins, comprises at least one amine having at least one amino group (I). Curing agent for curing epoxy resins, comprises at least one amine having at least one amino group of formula (I). R : H or 1-12C alkyl; Y1 : H, monovalent 1-12C hydrocarbyl, 1-12C alkoxy or 1-12C aryloxy; and b : 1 or 2. Independent claims are also included for: (1) preparing the curing agent, comprising carrying out reductive alkylation of at least one primary amine with at least one carbonyl compound of formula (III) to obtain the amine having (I); (2) an epoxy resin composition comprising at least one epoxy resin and at least one above curing agent; (3) a cured composition obtained by curing the above epoxy resin composition; and (4) articles containing the above cured composition.
