Self-sealing elastomer composition that can be used especially as a puncture-resistant layer in an inflatable article, comprising: as predominant elastomer, an unsaturated diene elastomer; between 30 and 90 phr of a hydrocarbon resin; and 0 to less than 30 phr of a filler. Also disclosed is an article such as a tire provided with a puncture-resistant layer comprising the self-sealing elastomer composition. The puncture-resistant layer is advantageously combined with an airtight layer, for example based on butyl rubber, so as to form, in the inflatable article, a puncture-resistant airtight laminate.
