Heatable composite pane for a projection assembly

A composite pane comprising:

• an outer pane, an inner pane, and a thermoplastic intermediate layer arranged between the outer pane and the inner pane, wherein
• the outer pane and the inner pane have in each case an outer face and an inner face, and the inner face of the outer pane and the outer face of the inner pane face one another,
• a first masking strip, which is arranged regionally on the outer face of the inner pane or the inner face of the outer pane,
• an electrically conductive coating, and
• a reflection layer, which is adapted to reflect light,
• wherein the reflection layer is arranged spatially in front of the first masking strip when viewed from the inner pane toward the outer pane, wherein the first masking strip overlaps the reflection layer at least in one region,
• wherein a high-refractive-index coating having a refractive index of at least 1.7 is arranged at least in a region of the inner face of the inner pane that is in overlap with the reflection layer, and wherein the reflection layer is arranged spatially closer to the outer face of the outer pane but spatially farther from the inner face of the inner pane than the high-refractive-index coating.
