We present the integrated J, H, K, L, M and N magnitudes and the colours involving infrared bands, for an extensive set of instantaneous-burst binary stellar populations (BSPs) by using evolutionary population synthesis (EPS). By comparing the results for BSPs WITH arid WITHOUT binary interactions we show that the inclusion of binary interactions makes the magnitudes of populations larger (fainter) arid the integrated colours smaller (bluer) for tau >= 1 Gyr. Also, we compare our model magnitudes arid colours with those of Bruzual & Charlot (2003, hereafter BC03) arid Maraston (2005, hereafter M05). At last, we compare these model broad colours with Magellanic Clouds globular clusters (GCs) arid Milky Way GCs. In (V-R)-[Fe/H] and (V-I)-[Fe/H] diagrams it seems that our models match the observations better than those of BC03 and M05.
