Zusammenfassung:	Disclosed are an insulating film composition produced by adding a metal nitrate and/or a metal nitrite, a method for producing the same, and a highly weatherable electrical steel sheet using the same. According to the present invention, the insulating film composition comprises: a metal phosphate (Mx_(=-3)(H_3PO_4)_y=_1-3); and an organic-inorganic composite in which a functional group included in an organic resin is substituted with inorganic nanoparticles, wherein a raw consumption rate of a metal (M) element is 100-250 % with respect to 100 % of a content of a phosphorus (P) element when calculating the integral value of an energy peak in energy dispersion X-ray spectroscopy (EDS) analysis of the insulation film composition. The insulating film composition according to the present invention has the effect of dramatically reducing the number of unreacted free phosphoric acids. 금속 질산염 및/또는 금속 아질산염을 첨가하여 제조되는 절연 피막 조성물, 이의 제조 방법 및 이를 이용한 고내후성 전기강판에 대하여 개시한다. 본 발명에 따른 절연 피막 조성물은 금속 인산염(Mx=1~3(H3PO4)y=1~3); 및 유기 수지에 포함되는 관능기가 무기 나노입자로 치환된 유무기 복합재;를 포함하고, 절연 피막 조성물의 에너지 분산 X선 분광 (EDS) 분석 시 에너지 피크의 적분값으로 계산했을 때, 인(P) 원소의 함량 100%에 대하여, 상기 금속(M) 원소의 원소비율이 100~250% 이다.
