  In this paper we show that certain Feynman integrals can be expressed as
linear combinations of iterated integrals of modular forms to all orders in the
dimensional regularisation parameter $\varepsilon$ . We discuss explicitly the
equal mass sunrise integral and the kite integral. For both cases we give the
alphabet of letters occurring in the iterated integrals. For the sunrise
integral we present a compact formula, expressing this integral to all orders
in $\varepsilon$ as iterated integrals of modular forms.
