Which material is noted for forming colorless deposits on superglue fingerprints?

Colorless deposits that form on superglue fingerprints are primarily identified as a result of the reaction between cyanoacrylate (the primary component in superglue) and moisture in the environment. When superglue is fumed, the cyanoacrylate vapor adheres to the latent fingerprint and polymerizes when it contacts moisture, leading to the formation of a colorless deposit. This process enhances the visibility of the fingerprint, making it easier to analyze and catalog.

Water, specifically in the form of moisture or humidity in the air, is crucial for this reaction to occur. When latent prints, which may naturally carry traces of moisture or oils from the skin, come into contact with cyanoacrylate fumes, the combination produces a solid structure that is clear and easily recognizable against the background.

The other materials listed do not directly form the colorless deposits through this fuming process and therefore are not the correct answers.
